I have been thinking about "for" and "in"
lately. Yeah, I should watch more TV.
Personally I rather like having this loop,
even though I rarely use it. Is that a
I've heard it suggested that it is largely
pointless, and we should probably just use
'each' et al. instead.
But I don't see it ever going away, because
of its long history in Ruby and the many
lines of code that might potentially use it.
Matz, am I correct in guessing the for loop
will never go away?
