It should be called var_set() - better on name space pollution.

If is is a language element (like isset()) then you can avoid this problem.
I do find a lot of code, in simple scripts, that does just that.
It might be nice to extend it such that if the 1st argument is a list then the
first in the list which is set is returned, eg:
$var = var_set(($_GET['var'], $_POST['var']), 'default');
