Detailed Description

Maps identifier occurrences to a unique global name.

Identifiers are assigned a global name when they are declared using insert(); later, an (potentially scope-qualified) aidentifier occurrence can be mapped to the global name by calling lookup_global_name().

Global names are scoped using the name and type of the scope in which they were declared. Use the enter_scope() and leave_scope() functions around invocations of insert() to define the scope.
