LEXED-AST: An ambigious ast
+ EXTERNAL-GLOBALS: A list of symbols in keyword package
AST: An unambigious ast that represents the code block of a model
+ PRIMS: Primitives that can be sent to the parser and transpiler
DESCRIPTION:
PARSE takes a ambigious LEXED-AST and converts it to an unambigious one.
+ It also returns the primitives that are defined in the code file, including
+ ones generated from the EXTERNAL-GLOBALS, that can then be passed to both
+ the parser and the transpiler.
+
+ EXTERNAL-GLOBALS is a list of symbols representing global variables that
+ are not defined within the code. Normally these come from widgets defined
+ in the model file, but could arguably come from elsewhere.
This parser, unlike CLNL-PARSE:PARSE, should not be fed into the transpiler.
Rather, the ast that's returned can be queried with other functions included
in the CLNL-CODE-PARSER package to tease out necessary information. Some of
those things will involve code blocks that can then be transpiled."
