Good example!
In that case, I repeat my disappointment that PHP doesn't allow one the
option to indicate a constant reference!!
Alternatively, maybe PHP should throw an error if a literal is passed
(as in your 2nd example), but cope with temporary variables - although
there's probably a caveat I'm not seeing with that either...
