I have long thought that the compiler might recognize 

	if(defined(...))

as a special case and use a different truth standard for evaluation
of ... rather than invoking the defined layer, and that would be
a wee bit faster.  Someone would have to code it though, which would
be difficult.  Same goes for exists.
