>> Perhaps join() ought to be a built-in function?
IMO, builtin join ought to str()ify all the elements in the sequence,
concatenating the results. That seems an intuitive interpretation of
'join'ing a sequence. Here's my Python prototype:
def join(seq, sep=''):
if not seq:
return ''
x = str(seq[0])
for y in seq[1:]:
x = x + sep + str(y)
return x
