Subject: Enumerators with hashslice - RubyConf addenda

Hi all,

With a little help from the fine folks on IRC, here's a bit of addenda
to my Ruby Conf talk - quick enumerators using hashslice and ranges:

require "hashslice"
h = {}
h[*(1..26)] = [*("a".."z")]

h[1] -> "a"
h[26] -> "z", etc

Perhaps a bit Perl-like in obfuscation, but might be handy.

Michael Granger also pointed out that it's useful for value
transposition (if that's the correct term):

h = {:name1 => "Matz", :name2 => "Nobu"}
h[:name1,:name2] = h[:name2,:name1]

Enjoy!

Regards,

Dan
