Functions
Perform the given action for each child phrase of this phrase.
Perform the given transformation for each child phrase of this phrase, writing the result of the transformation back into this phrase. This phrase must be mutable.
Create a new list phrase with the elements of the given list phrase appended to the ones in the receiver.
If the receiver is mutable, make its subobjects immutable and return it. Otherwise, make a mutable copy of the receiver and return it.
Emit code to push each value produced by the expressions of a list phrase or permuted list phrase.
Emit code to perform the effect of this phrase, leaving the operand stack the same as before these instructions.
Emit code to perform this phrase, leaving its result on the stack.
If this phrase is a sequence, take any statements within it that are also sequences, and flatten them all into one sequence, returning the List of statements. Handle first-of-sequence phrases correctly, allowing the resulting structure to be up to two layers deep.
Compile this block phrase into a raw function, recording within it that it was compiled within the given module.
Test whether this phrase has a PhraseKind that is equal to or a subkind of the given PhraseKind.
Validate this phrase without also visiting its subphrases.
Properties
Answer the list phrase that provides arguments to this send phrase. If this is a macro invocation, these are the arguments supplied to the macro's output, which must be a send phrase.
Answer the declaration phrase referenced by this variable use phrase. If this phrase is a macro invocation, answer the declaration referenced by the variable use produced by the macro.
Answer the type of the variable, constant, or argument declared by this declaration phrase.
If this phrase is an assignment, answer the expression that produces the value to assign. If this phrase is an expression-as-statement, answer the expression to treat as a statement. If this phrase is a super-cast, answer the expression that produces the actual value to send. If this phrase is a macro, use the above rules on the output of the macro.
Answer the number of expressions in this list phrase.
Answer the tuple of expressions in this list phrase.
This is an expression acting as an argument, a recursive list phrase of arguments (perhaps permuted), or a super-cast. Answer whether it either is or contains within the recursive list structure a super-cast phrase.
Answer the phrase producing the value to be assigned during initialization of a variabledeclaration. If there is no initialization expression, answer nil.
Answer whether this variable use is the chronologically last time its variable will be used within this block.
Answer whether this phrase is a macro substitution phrase.
Extract the last expression of this [listListPhraseDescriptor phrase. The client must ensure there is at least one, and that this is a list phrase.
This module constant's actual value, or this module variable's actual variable.
Answer a marker phrase's marker value, which can be any AvailObject.
The tuple of declaration phrases accessed by this block phrase. This value is set during code generation, even if the block phrase is immutable. It should not be made visible to the Avail language.
The phrase that this macro phrase generated to use as its replacement.
Answer the permutation from a permutation list phrase. The permutation is a tuple of integers between 1 and the number of elements, where each value occurs exactly once, and the tuple is not in ascending order.
The CheckedMethod for phraseExpressionType.
Answer this phrase's PhraseKind.
Answer this block phrase's starting line number in the source.
If this is a super cast phrase, then answer the type by which this argument should be looked up. If it is not and does not contain a super cast phrase in its recursive list phrase structure, then answer bottom. Otherwise create a (recursive) tuple type where elements that are supercasts provide their lookup types and the rest provide bottom.
Answer the token which was used in the construction of a variable use phrase, a declaration phrase, a literal, or a macro that resolves to one of those.
Answer the variable use phrase that is used by this reference or assignment.
