A variable entity including a reference to its types' definition.
A ScalaTest tag that enables us to focus attention on particular tests rather than running all of them each time.

Check for non-local variable and procedure accesses.
Check for non-local variable and procedure accesses. In the L3 language non-local variable accesses are disallowed, unless they are to a variable at the top level. Non-local procedure accesses are just disallowed.

Default is true; override with false if you want actual results

The program entity referred to by an identifier definition or use.
The program entity referred to by an identifier definition or use. In the case of a definition it's the thing being defined, so define it to be a reference to the declaration. If it's already defined, return a entity that indicates a multiple definition. In the case of a use, it's the thing defined elsewhere that is being referred to here, so look it up in the environment.
The entity for an identifier definition as given by its declaration context.
The entity for an identifier definition as given by its declaration context.
The environment containing bindings for all identifiers visible at the given node.
The environment containing bindings for all identifiers visible at the given node. It starts at the module declaration with the default environment. At blocks we enter a nested scope which is removed on exit from the block. At constant and type declarations the left-hand side binding is not in scope on the right-hand side. Each identifier definition just adds its binding to the chain. The envout cases for assignment and expression mean that we don't need to traverse into those constructs, since declarations can't occur there.
Blocks that are immediately inside procedure decls do not introduce new scopes since the procedure itself does.
Blocks that are immediately inside procedure decls do not introduce new scopes since the procedure itself does. This computation overrides the one earlier that pushes a scope for all blocks. Don't include the procedure name in the scope of its own body.
Similarly for envin we don't need to leave a scope for a procedure block, since we didn't enter one.
Similarly for envin we don't need to leave a scope for a procedure block, since we didn't enter one. The IdnDef that is for a ProcDecl needs to be in the outer scope, but not in the scope of its own body. All arguments and local declarations go in the nested scope.

Is an expression expected to be constant or not? Either the expression is the root of an expected constant expression or its parent expression is expected to be constant.

Make tests that process the files in path.
Make tests that process the files in path. name is an identifying
name for this set of tests. All files whose names end in srcext are
processed. Processing is done by the function compile which must
return either Some (s) where s is the output or None if processing
failed. If srcext is .x and resext is .y, then the expected result
for foo.x is found in file foo.y. If optinext is Some (z), then
foo.z is used for standard input, if it exists, otherwise the string
indefault is used. A test fails if either the processing fails or
it succeeds with the wrong result. argslist is used to specify the
sets of command-line arguments that you want to use. Each test is
run with each set of arguments. The default is an empty argument list.

Return true if the expression can legally appear on the left-hand side of an assignment statement.
Return true if the expression can legally appear on the left-hand side of an assignment statement. At this level only allow identifiers of variables or things we don't know anything about. The true default is used so that this computation can be used in redefinitions.

Parameters are variables too.
Is an expression constant or not? Unknown entities are constant.
Is an expression constant or not? Unknown entities are constant. Strictly speaking we only need to support integer expressions here, but we treat Boolean ones as constant in the same way so that we avoid spurious errors. Type analysis will reject Boolean constant expressions anyway.

Is this expression the root of what is expected to be a constant expression? At this level only expressions on the RHS of a constant declaration have this property.

Sanitise the output from a test.
Sanitise the output from a test. Remove any output that doesn't make sense to this program. I.e., if we are running a program that performs tasks 1-m, then any lines marked with [p], where p > m should be removed before comparison. Also, there can be three numbers, a'la [p,q,r] where p is as before and q (r) are lower (upper) inclusive bounds on the language level to which this output should apply. If p is omitted, the output applies to all task levels. If p is given, but q and r are omitted, the output also applies to all language levels.

ScalaTest by default only shows the unqualified class name when it displays the name of the suite.
ScalaTest by default only shows the unqualified class name when it displays the name of the suite. If a suite class name is used in more than one package we can't tell them apart. Here we override the name that is printed so that we get a project relative source file name as well.
This definition assumes that the test suite resides in the library project, that the name of the suite class is the same as the basename of the file and that the file is located in the folder given by the package name.
