Hi Marc, I actually discovered it after posting this gem to github. I am pretty impressed by the work you have done.
You have very well implemented it in the way a monad should be implemented, besides that the Monad module needs to be included after defining bind - I think this can be better solved with inheritance maybe.

I am trying to create something more idiomatic to ruby. Hence #value instead of #get_or_else. Also doing subsequent map, select etc is very functional but my primary idea was to safely support (trainwreckish) expressions like
User.name.capitalize. Also I often work with nested Hashes and need to reach deeply inside of them so my code is sprinkled with things like some_hash.fetch(:one, {}).fetch(:two, {}).fetch(:three, "unknown").
With the method_missing on None I can safely and consisely do:

some_hash.[:one][:two][:three].('unknown') or with injecting a method_missing into hash even better:
some_hash.one.two.three. 'unknown' or some_hash.one.two.three.or 'unknown' or some_hash.one.two.three.value 'unknown'

Thanks Piotr, sounds like you have different goals then. Because of how dynamic Ruby is, I wanted my code to be very clear and obvious when you have an Option, and when you have the underlying value. But your approach may be very popular, as I've seen a lot of code that seems to want to do what you are trying to do. Good luck!
