A Ruby hash, Luxury Touring Edition

Wherein Ruby's hashes are made slightly nicer

map.rb, quality software by Ara T. Howard:

the awesome ruby container you’ve always wanted: a string/symbol indifferent ordered hash that works in all rubies

m = Map.new

m[:a] = 0
m[:b] = 1
m[:c] = 2

p m.keys #=> ['a','b','c'] ### always ordered!
p m.values #=> [0,1,2] ### always ordered!

m = Map(:foo => {:bar => 42})
s = m.struct # maps can give back clever little struct objects
p s.foo.bar #=> 42

I like little tactical improvements to the Ruby standard library that give it a slightly more modern feel.
