>From perldoc perl:

   perldebguts    Perl debugging guts and tips
   perlclib       Internal replacements for standard C library functions
   perlguts       Perl internal functions for those doing extensions
   perlcall       Perl calling conventions from C

   perlintern     Perl internal functions (autogenerated)
   perlapio       Perl internal IO abstraction interface
   perlhack       Perl hackers guide

There may be some others of importance, but these should be enough to
start with.
