I doubt it will. Even in Ruby, singleton methods are implemented with
classes under the covers.

The fact that Ruby instance variables appear on demand, and so references to
instance-vars cannot be directly mapped to integer offsets from a known
class definition, will likely mean some performance trade-off.
