I'm not given to hating anything :)

It would need to be done within the profiler, like it already does
for the accept() builtin function. You're not the first to ask
so I've created a ticket: https://rt.cpan.org/Ticket/Display.html?id=83381

In what way is having DB::disable_profile in the profile a problem?
I think there is code in NYTProf to hide the disable_profile, so
perhaps that's not working. I'll look into it.
