Devel::Cover tells you a lot more than just whether a line of code was
executed.  Consider a line like this:

  do_something if($foo || $bar);

Devel::Cover will tell you which of the three possible conditions were
covered by your tests, those being:
  * neither $foo nor $bar are true;
  * $foo is false, $bar is true;
  * $foo is true and we don't care about $bar

I'm surprised that you can bet NYTProf working but not Cover - in my
experience, they either both work easily or both fail horribly.
