That still doesn't help at all in the case where the function returns 
something, but you simply don't care about the result.

That said, I don't think this issue is big enough to start radically 
changing how SELECT without INTO works -- you can always get around this 
limitation by SELECTing into a variable, as David mentioned in his 
original message.  It's annoying, but it works.
