Detailed Description

This is a derived symbol class for named items that exist in a scope.

These include:

• identifiers
• subprograms (procedures and functions)
• instances (e.g., u1 : foo port map (...); has the name u1)

These items can all be found in a symbol table in their local scope.

Subprograms not only have scope, but they also have an associated synbol table.

Exceptions (e.g., objects that are NOT sym_scoped, but have scope information)

• Processes

  Although a process may have a name, its not clear that this name is useful for anything, except adding code reability. A process is not looked up in the symbol table, so it is not a sym_scoped object (or even a sym derived object). But a process _does_ have an associated symbol table.

• Packages

  A package has scope (e.g., local types, constants, etc). But packages are in the global scope. Its not clear that packages will survive after elaboration. </p.
