           Summary: TypeInfo_Typedef has incorrect implementation of next()
           Product: D
           Version: 1.022
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: tomas famolsen.dk


This assertion fails:

assert(typeid(int_t).next is typeid(int));

It should be defined as:
TypeInfo next() { return base; }

Not:
TypeInfo next() { return base.next(); }
.. as it is now.

oups forgot something. the test case is:

typedef int int_t;
assert(typeid(int_t).next is typeid(int));

again so trivial, yet fixing has taken almost a year and has still not
happened.

This is actually the intended behavior. All the virtual functions for a typedef
"see through" any layers of typedefs and work on the base type. This makes code
that walks the typeinfo's simpler.

To get the base of a typedef, cast the TypeInfo to a TypeInfo_Typedef, and get
the .base.
