Would it be impossible to add nonblocking promises to Ruby? 

I mean an eventualt operator (for "eventual send" as described in
http://www.skyhunter.com/marcs/ewalnut.html#SEC18) in addition to the
current immediate method calls.

Could it in fact not be implemented in Ruby itself?

Just a thought.
