This might well be the reason why this paragraph was written.  But still I 
see a great fallacy here: if a compiler knows that a non-intrinsic 
function will never be allowed in an initialization expression, then why 
even bother looking ahead?  The way this paragraph was written and 
inserted in the standard is odd.  It gives a reader an illusion that user 
defined functions can be used perfectly in initialization expressions.
