Re: computing with characters

However, join() is really bizarre. The list rather than the
separator should be the leading actor.

Certainly *not*! This would be the way ruby does it, and IMHO it does not make sense to add join as a string-processing related method/functionality to a general purpose sequence type. And as others have pointed out, this would also mean that e.g.

def sgen():
for i in xrange(100):
yield str(i)

sgen.join(":")

wouldn't work or even further spread the join-functionality over even more objects.

An argument for the original ord/chr debate btw is orthogonality: if you want ord to be part of a string, you'd want chr to be part of ints - which leads to ugly code due to parsing problems:

(100).chr()
