[development] So confused about arg(...)

Call me old school, but calling the same function with the same argument
twice in a row is wasteful. I see this tendency to just call the same thing
a lot rather than storing it in a variable and reusing it, and I don't like
$a0 = arg(0);
$a1 = arg(1);
$path = "$a0/$a1";
drupal_set_message('stuff' . $path);
$variables['nancy'] = $hook . $path;
This does not address why you are seeing what you are seeing. Use a debugger
like xdebug to see what really is going on there.
