It's funny you should say that, because just today I was staring at a 
couple of foreaches that were giving me compiler errors and scratching 
my head.  Turns out I had written this:

      foreach(i,ang, angles) {
          ...
      }

Now maybe you can see right away what's wrong, but in my somewhat sleepy 
state and with my preferred ProggyTT programming font, I just didn't 
notice the missing pixel there.   It's much harder to mistake a comma 
for an 'in'.

Hmm, that doesn't sound like a scientific study.  Python has many more 
users than D despite the fact that apparently most people don't like it.

That said, I think trying to change such a basic part of D's syntax at 
this point is a bad idea.
