Except to the human reader, who can be forgiven for thinking "What the 
fudge is that semicolon doing there???" (or even less polite).

I don't know of any language that uses semi-colon as an operator.

That looks like a bug magnet to me. Consider what happens when (not if) 
you write (a,b) instead, or when you write

items = (x; y)

and it happens to succeed because x and y are iterable.

To be perfectly honest, and no offence is intended, this suggestion 
seems so wacky to me that I'm not sure if you intended for it to be 
taken seriously or not.
