Hi
Please confirm that:
`
    assert(false, __FUNCTION__ ~ "This is an error message");

Will _not_ trigger GC issues, as the text is entirely known at compile 
time.

Best regards

One way of forcing compile-time evaluation in D is to define an enum 
(which means "manifest constant" in that use). I used @nogc to prove 
that there is no GC allocation as well:

@nogc
void main() {
  enum msg = __FUNCTION__ ~ "This is an error message";
  assert(false, msg);
}
