A wild wild guess is that there was code in the compiler that
used to require it (after all, it was required a long time
ago), and somehow it got reactivated by accident.
But wild guesses don't help fix bugs :)
In doing a search through my email of the dmd-internals mailing
list, I don't see opCmp anywhere.
Ah, I see. I got the impression that he thought it was a
deliberate change, which is why he was so irate. Maybe someone
should mention this in the thread.
