And thanks to the time machine, str.join('', seq) does this already:

Python 2.2.2 (#1, Feb 24 2003, 19:13:11)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> str.join('',['a','b','c'])
'abc'

Who needs a new builtin?  :)
