What's happening here is that calls to other subroutines are being made but
NYTProf isn't able to determine the calling location correctly so the calls
-don't appear in the report in the correct place. (This is more common with

+don't appear in the report in the correct place.

+Using an old version of perl is one cause (see below). Another is calling
+subroutines that exit via C<goto ⊂> - most frequently encountered in
+AUTOLOAD subs and code using the L<Memoize> module.
In general the overall subroutine timing is accurate and should be trusted
more
than the sum of statement or nested sub call timings.
