An odd request.. I want to have optional function arguments
that *aren't* defined unless values are explicitly passed. Sorta
the equivalent of
function foo($arg1_required, $arg2_optional=undef)
if (isset($arg2_optional)) {
print "explicit";
}
else {
print "not passed

No, I said 'undef' because I mean 'undefined'. The argument
can have *any* value; I need to know when
