[...] get str.join to support objects which implement the buffer interface as one of the items in the sequence?

Something like: y = 'hello world' buf1 = buffer(y, 0, 5) buf2 = buffer(y, 6) print ''.join([buf1, buf2]) should print "helloworld"

This is incompatible with the recent proposal making str.join automatically str-ify its arguments. i.e.:

''.join(['a', 12, 'b']) -> 'a12b'.

I don't feel strongly about either proposal, I just thought I'd point out that they're mutually exclusive.
