So I've had a pretty fun bug today when porting some code over to D.
When I port C code to D, first I do a one-to-one translation and make
sure everything works before I try to make use of any D features.
Here's a function snippet, try to figure out what's wrong with the
code (don't worry about type definitions or external variables yet):

Ok that's quite a bit of code. Let's cut to the chase:
if (mmioRead(hmmio, cast(LPSTR)&drum, DRUM.sizeof != DRUM.sizeof))
{
mmioClose(hmmio, 0);
return szErrorCannotRead;
}

Maybe DMD could warn on nonsense of the form x != x.

That would help in this particular case, but not in general.
