I hate it when that happens.

Yeah. I guess the reason I do the latter is b/c I want the code to
reflect what I am actually trying to test. I don't really want to test
the trueness of @foo, I want to test for it's existence. But in perl
the operation is overloaded. Feh.
I think I will test for defined $foo_in[0] instead.
