I was wondering about that, actually. Kinda reminds me
of years ago when someone wanted to know why they could
not do something with a zero-width pen in VB (or something
like that). The guy was puzzled because he said he
could do it in C. I was then puzzled because I didn't
realize that C _had_ a concept of "pen"...
