"foo, bar, baz", just like any other function. This is important because
we don't use the weird keyword-ized syntax when dumping out function
calls in rules and suchlike. Also, in general it's preferable to not
prevent users from creating their own functions that happen to be named
like a system function. (I think the current code fails to achieve that
last goal because of the forced function name remapping, but perhaps it
should be fixed if we're going to mess with it.)
