digitalmars.D.bugs - [Issue 19029] New: Provide alias symbol name trait


          Issue ID: 19029
           Summary: Provide alias symbol name trait
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd

Currently there is no way to get the name of the alias for a symbol type.

For example the following:
void main()
    import std.traits;
    size_t s;

    pragma(msg, typeof(s).stringof);
    pragma(msg, mangledName!(typeof(s)));
    pragma(msg, mangledName!s);

For code generation porpoises (eg. generate C wrapper code) there is no way to
get the type of `s` as `size_t` because `size_t` is an alias.

A new trait, `__traits(aliasName, symbol)`, could be used to retrieve the alias
name for a symbol type.

This trait will return the name of the concrete type if the symbol type is not
an alias.
