A Ruby port of Scala's for comprehension to be used in tandem with Option.
Add this line to your application's Gemfile:
gem "for-yield"
And then execute:
$ bundle
Or install it yourself as:
$ gem install for-yield
To use the for comprehension helper:
for_ Option(1), Option(2) do |a, b|
a + b # => 3
endThis enables unwrapping multiple Option values into a block.
