pfunc - grep for perl functions

       Michael G Schwern <schwern@pobox.com>

pfunc searches the named FILES for all calls to the given subroutine.  It will report back the file and
       line number each call is found on along with what sort of call it is

           function            foo()
           class method        Class->foo()
           object method       $obj->foo()

           $ pfunc isa /usr/share/perl/5.6.1/*.pm
