A_Token
A_Token is an interface that specifies the token-specific operations that an AvailObject must implement. It's a sub-interface of A_BasicObject, the interface that defines the behavior that all AvailObjects are required to support.

Functions
Turn the receiver into an indirection to the specified object.
Disconnect this token from its internal cache of what comes next.
Utility method for decomposing this object in the debugger.
Retrieve the object's {@linkplain AbstractDescriptor descriptor}.
Answer whether the receiver and the argument, both A_BasicObjects, are equal in value.
{@inheritDoc}
Answer whether the receiver, an object, and the argument, a byte string, are equal in value.
Answer whether the receiver, an object, and the argument, a byte tuple, are equal in value.
Answer whether the arguments, an object and a compiled code, are equal.
Answer whether the receiver equals the argument.
Answer whether the receiver equals the argument.
Determine whether the receiver is an enumeration with the given set of instances.
Answer whether the receiver, an object, and the argument, a fiber type, are equal in value.
Answer whether the receiver, an object, and the argument, a function type, are equal.
Answer whether the receiver equals the argument.
Answer whether this value equals the given list phrase type.
Answer whether the receiver equals the argument.

Answer whether the receiver equals the argument.
Extract a field from an object.
Extract a field from an object, using a one-based index into the field slots. This requires knowledge of the ObjectLayoutVariant, since the same field is at different indices in different variants.
Extract a field from an object, or answer null if it's not present.
Add or replace a field of an object.
Extract a field type from an object type.
Extract a field type from an object type, using the given field index, which is specific to an ObjectLayoutVariant.
Extract a field type from an object type, or null if it's not present.
Dispatch to the descriptor.
Answer the number of integer slots. All variable integer slots occur following the last fixed integer slot.
Given a module in the process of being compiled, answer whether this token was constructed by the compiler from the module's source.
Dispatch to the descriptor.
Dispatch to the descriptor.
Answer whether this token is a literal token, such as a string or number.
The line number of this token in the source file.
Extract the literal value from this token. It must be a literal token.
Answer this token's string representation converted to lower case.
Dispatch to the descriptor.
The receiver is marked with an IMMUTABLE descriptor, but its subobjects have not yet been made immutable. Scan them now, and do any additional fix-ups necessary for the kind of object.
Dispatch to the descriptor.
The receiver is marked with a SHARED descriptor, but its subobjects have not yet been made shared. Scan them now, and do any additional fix-ups necessary for the kind of object.
Dispatch to the descriptor.
Dispatch to the descriptor.
Answer a name suitable for labeling a field containing this object.
Answer the LexingState that follows this token, or null if it hasn't been set yet.
Answer the pojo AvailObject containing the ]LexingState that follows this token, or nil if it hasn't been set yet.
Answer the number of object slots in this AvailObject. All variable object slots occur following the last fixed object slot.
Recursively print the receiver to the builder unless it is already present in the recursionMap. Printing will begin at the specified indent level, measured in horizontal tab characters.
Dispatch to the descriptor.
Answer whether the objects occupy the same memory addresses.
Dispatch to the descriptor.
Given a module in the process of being compiled, alter this token to indicate that it was created directly from that module's source.
Replace the object's {@linkplain AbstractDescriptor descriptor}.
Dispatch to the descriptor.
Set this token's next LexingState.
Replace my descriptor field with a FillerDescriptor. This blows up for most messages, catching incorrect (all, by definition) further accidental uses of this object.
Answer whether to show value-specific content in the file name for the debugger.
Create and answer a LexingState corresponding to the start of this token. It should not be used for subsequent parsing/lexing.
Answer the TokenDescriptor.TokenType of this token.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden immutable->mutable references. Only used during makeImmutable.
Follow indirections until a non-indirection is reached. Replace each indirection's target with the ultimate target, even if it would cause the otherwise-forbidden shared->unshared references. Only used during makeShared.
Answer the number of variable integer slots in this object. This does not include the fixed integer slots.
Answer the number of variable object slots in this AvailObject. This does not include the fixed object slots.
Properties
Is the receiver an Avail extended integer?
Is the receiver an Avail IntTupleDescriptor? This is conservative, in that some object tuples may only contain ints but not be reported as being int tuples.
Is the receiver an Avail LongTupleDescriptor? This is conservative, in that some object tuples may only contain longs but not be reported as being long tuples.
Is the receiver an Avail two-byte string?
Is the receiver an Avail unsigned byte?
