And they say you can't write obfuscated code in Python :)

I would have expected "join" to be a method on the sequence, if 
anything. As in "s = lst.join('')". In fact, I looked for it, as I 
*knew* I'd seen it used before as a method, I just didn't expect it to 
be in the string class.

I think I'll just stick with string.join for the time being. As it turns 
out, there's more than one way to do it, even in Python ;)

You're right, of course.
