The idea comes from http://stuartsierra.com/2009/01/18/tests-are-code. It's a neat idea, probably best suited for functional programming where one-liners are the norm and not the exception. BUT ... I think we could do it in Perl. Something like: 
use Test::With;

sub foo : WithTests( 2 ) {
    my ($x, $y) = @_;
    return $x + y;
} with_test {
    cmp_ok( foo( 4, 3 ), '==', 7 );
    cmp_ok( foo( -6, 2 ), '==', -4 );
};

I'm not even sure if that syntax will work, but it looks appealing. :-)
My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
