if 
See "Implementing if in Ruby" for more information.
Requirements
This library is tested on Ruby 1.8.7 and later but benefits from Ruby 1.9's hash and lambda literal syntax.
"truthy".if -> { "I'm true!" }, else: -> { "I'm false!" }
# vs.
"truthy".if proc { "I'm true!" }, :else => proc { "I'm false!" }Usage
require "if"
"Some truthy object".if -> { "I'm true!" }, else: -> { "I'm false!" }
#=> "I'm true!"
nil.if -> { "I'm true!" }, else: -> { "I'm false!" }
#=> "I'm false!"
# Or, if you only care about side-effects and not return value:
"Some truthy object"
.if_true { puts "I'm true!" }
.if_false { puts "I'm false!" }
# "I'm true!"
#=> "Some truthy object"
nil
.if_true { puts "I'm true!" }
.if_false { puts "I'm false!" }
# "I'm false!"
#=> nilLicense
