http://www.rubycentral.com/book/

it feels a bit like "v1.0" documentation and tends to be a bit too
"for tradtional programmers" as a bridge to the ruby way of thinking
for my tastes.  (i'd rather be explained the "accepted style" upfront,
personally.)  but it is by far one of the best books on howto
programming, let alone learning ruby, i've read.

some where in there it explains about begin...end, then iirc talks
about blocks, then explains about { }.  i would lump that together,
personally, but that's the "v1.0" thing.  p.s. the "pragmatic
programmers" are pretty on the ball about improving the process of
programming; their other book is worth reading as well.
