Subject: Higher-order messaging in Ruby

Hi all.

Jus stumbled upon interesting post here:
http://legacyofthemob.se/istari/2006/10/08/higher-order-messaging-in-ruby/

One more trick allowing goodies like

[0,1,2,3,4].where.nonzero? 
# => [1,2,3,4]

[0,1,2,3,4].do_collect * 2
# => [0,2,4,6,8]

And so on.
Wow, IMHO.
