Toby,
@include 'Foo.php';
should do the same thing, but I haven't tried it. Rather, I use
require_once on all my files; there's a reason I include them - because
I need them.
But you're right - include paths make things very difficult to determine
if a file exists or not. You could parse the entire include path, but
it's a lot of unnecessary work.
