Writing a *simple* node class is easy, but a full-featured one that supports 
things like comparison and easy iteration is a bit more work. So various people 
write partial implementations with only the features they need, and they all end 
up being incompatible. So beyond being able to use it, the other thing is that 
having an implementation in the standard library acts as a de facto interface 
standard, making it easier to write common code to operate on tree structures.

All it would take to make it happen is a PEP, an implementation and a champion 
with some persuasive ability :)

Cheers,
Nick.
