Global constants like enums are represented in the AST as identifiers. These identifiers can be looked up in the AST reference map. If there is an entry in the reference map, we can try to fold it as a constant and to turn it into a literal. This reduces the size of the AST and unlocks more optimization opportunities.

Global constants like enums are represented in the AST as identifiers. These identifiers can be looked up in the AST reference map. If the entry in the reference map has a value associated with it, we can treat it as a constant and attempt to turn it into a literal.
This reduces the size of the AST and unlocks more optimization opportunities.
