We could try some sane defaults (for if ($v)).
yes, in case there are some.
For example that's what perl does:
undefined "" string 0 other integer
$foo eq undef true true false false false
$foo == undef true true true true false
$foo eq "" true true false false false
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
in true.
what would make sense to me is that comparing an undefined thing to
anything that is defined, would result in false.
$foo == 0 true true true true false
again "" == 0 makes no sense.
