Says YuckFoo:
It never made sense to me why no commas are allowed after the filehandle in a printf with parentheses. I think even if someone could explain why printf(OUT "foo\n"); is the reasonable or logical choice, I would still not be satisfied.

It's not just the reasonable, logical choice, it's pretty much the only choice. If there were a comma after the filehandle, then what would this do? 

    print $x, $y;

Are you printing the contents of $y to filehandle $x? Or are you printing the contents of $x and $y to stdout?

This is the same old problem that you always have when there's an optional argument at the beginning of an argument list instead of at the end: How do you tell if the optional argument is there or not? Sometimes external factors allow you to tell; when there are no such external factors, you have to invent a syntactic distinction.
