TFutureMaker implements #doesNotUnderstand:, which catches all non-
implemented messages, and turns them into a future send. This is a
"generic proxy", it does forward all messages without specifically
having to declare each one.
Also, the #future send is usually optimized by the Croquet compiler,
but that does not change its behavior, just its efficiency.
