Subject: [sv-ec] Issue 64 / Mantis 2598 - references to parameters in
parameterized classes

Mantis 2598 uses the following example:

   class C #(type TC = int);
      parameter type LTC = real;
   endclass


Question:

    1) Is "C::TC i;" legal?

    No -- the first paragraph of 8.24.1 is clear that "::"
    is not legal for a parameterized class in this context.

    2) Is "super.TC or super.LTC" legal?

    No -- at this point the only legal "dotted name" with a
    type is the interface_name form defined for typedefs in
    6.18.

    Note -- I would not object to allowing super.TYPE_NAME
    as a type reference in the context of a typedef.

    3) is C#()::TC legal?

    Yes.  In 8.24.1 we have:
         When referring to the default specialization as the
         prefix to the class resolution operator, the explicit
         default specialization form of #() shall be used.

    So C#()::TC refers to the type TC within the default
    specialization of C (i.e. int).


I don't think we need to take any action here unless there are additional
questions.
