          Issue ID: 15042
           Summary: [REG2.068] isInstanceOf fails when a template argument
                    is an instance of the tested template
           Product: D

                OS: All
            Status: NEW
          Severity: regression
          Priority: P1

I have a templated struct that emits an error when you pass in something else
than "void" or another instance of itself. The following worked with 2.067, but
fails with 2.068.1:


import std.traits;

struct RC(Parent)
    static assert (is(Parent == void) || isInstanceOf!(RC, Parent), "This used
to compile in 2.067");

alias Regression = RC!(RC!(void));
