Pattern matching on Maybe

[ianks]

I would like to be able to do somehting like this

Maybe(nil).match do
  Some(s) { |v| s }
  None(n) { |v| SomeObject.new }
end #=> SomeObject.new

Is this possible/is there a better pattern than this for having this behavior?

did you try Maybe(nil).value_or SomeObject.new ?
