Well, there's this:

	for in in in in; do echo $in; done

I haven't applied your patch yet, so I don't know whether it fouls up
the above, but clearly a parameter named "in" can only appear in the first
position, and everything else has to be taken as a keyword first and only
a parameter name otherwise.

What if you attached it to the "foreach" keyword, but not "for"?  So then
one would have to write

	foreach x y z (p d q) ...

Just a thought.
