Getting hash values as an array keeping order in ruby 1.8.3

I'm doing:

{:a => 'hello', :c => 'lovely', :b => 'word'}.values

It returns:

[0] "hello",
[1] "word",
[2] "lovely"

Why did the order change? Any way to easily return the values in the order they were defined in hash?

Rails implements an OrderedHash for Ruby version < 1.9. You can consider implementing it if you're not using Rails.
