I understand that this is not sufficient because of the following
circumstance:

$var = ifsetor($_GET['test'], foo());

foo() is ALWAYS evaluated with the user-space function you wrote. I
understand that we don't want foo() to be called unless it needs to be
returned (ie, we want to be able to short circuit the parameters)?

Now, maybe _I'M_ misunderstanding? (-: I don't have much knowledge of
internals, but is this even POSSIBLE as a function call, and not as an
operator?
