See other answers.  I just want to put in a plug (since you're still a
nuby :-) for using parentheses, especially in method definitions:

   def func(*args, &blk)

I know it looks sort of cool without them, but I find (and I'm pretty
sure I'm far from the only one) that I have more trouble parsing it
visually, especially when you get things like:

   def a b, c = 100

which is legal but, to my eye, too thin on visual cues.
