It certainly does have some caveats.  And according to at least one of 
them it may break badly in the future from a plausible compiler change.

Well, it's what I asked for, but using something that can be expected to 
break without warning.  I want to write code that I can forget after I test.

It would have been a great convenience, but that's a bit too high a 
price to pay for a convenience.
