yes, in case there are some.

if $foo is undefined, it is insane to me that it would be equal to empty
string "" or 0. also comparing two undefined things should not result
what would make sense to me is that comparing an undefined thing to
anything that is defined, would result in false.

again "" == 0 makes no sense.
