In the spirit of the perl don't module, here's the ruby maybe gem that provides three new constructs -- maybe, probably, and unlikely -- as shown here: 
require 'rubygems'
require 'maybe'
puts 'Maybe'
5.times do |x|
  maybe { puts x }
end
puts 'Probably'
5.times do |x|
  probably { puts x }
end
puts 'Unlikely'
5.times do |x|
  unlikely { puts x }
end
producing this 
Maybe
1
2
Probably
0
1
3
4
Unlikely
4
To install, download maybe-0.0.1.gem and run 
% sudo gem install maybe-0.0.1.gem
