I don't pretend to :)

This is what Carl Banks was saying below (that getting the length of 
something was generic operation)... Well, I suppose it sorts of make sense. I 
had the feeling that Python had been moving from a more procedural kind of 
language to a more object-oriented one (by having the "everything be an 
object"). But I'm beginning the see the logic in having a len() function (as 
opposed to a design wart).

Thank you,

Emm
