Higher-order messaging in Ruby

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.

magic_underscore_notation and &:_symbol? ? &:other : proc{|n|
n}.call(42)
(well I am just kidding with the last one).
