Here is a reduced test case. Before filing a bug report, just wanted to make
sure if I am doing something obviously wrong here.

import std.stdio;
struct Foo(IF, size_t N) { }
interface Bar { }
void main() {
  void printFoo(T: Foo!(IF, N), IF, size_t N)(T foo)
    if(is(IF == interface)) {
    writeln("Type: ", T.stringof);
  }
  Foo!(Bar, 1) foo;
  printFoo(foo);
}
