I don't understand, sorry.
Python programmers for sure can define singleton methods directly in a 
object without singleton classes, I guess perl folks too, since an 
object is mostly an hash (I may be wrong, not really good at perl).
Actually, only Java's anonymous classes seem somewhat similar to 
singleton ones.

I agree with you that some backward compatibility issues may be 
programmer-based, but I don't think this is a case.
