[Israel.pm] setting $!

Hello,

I have a function foo() which returns some scalar $s.

I'd like to be able to do something like this:

	my $s = foo() or die "foo: $!";

I'd like to  be able to assign my own string to $! to be
used right after a return from foo()  in case an undefined
value is returned.

What's the way to do this?
