errors. See also L</make HTML install work>, as the layout of installation tree
is needed to improve the cross-linking.
+The addition of C<Pod::Simple> and its related modules may make this task
+easier to complete.

=head2 Parallel testing
The core regression test suite is getting ever more comprehensive, which has
to review the ordering of the variables, to see how much alignment padding can
be removed.
-=head2 repeated code in filetest operators
-
-F<pp_sys.c> has a lot of partially repeated code in the filetest operators (for
-example C<pp_ftrowned>, C<pp_ftzero>, C<pp_ftsize>, and C<pp_ftmtime>,
-C<pp_ftatime>, C<pp_ftctime>). It would be good to investigate whether some
-of this could be refactored out into common static functions. A similar
-refactoring on F<utf8.c> saved about 1.5K of object code size.
-
=head2 bincompat functions
There are lots of functions which are retained for binary compatibility.
=head2 lexical pragmas
-Reimplement the mechanism of lexical pragmas to be more extensible. Fix
-current pragmas that don't work well (or at all) with lexical scopes or in
-run-time eval(STRING) (C<sort>, C<re>, C<encoding> for example). MJD has a
-preliminary patch that implements this.
+Document the new support for lexical pragmas in 5.9.3 and how %^H works.
+Maybe C<re>, C<encoding>, maybe other pragmas could be made lexical.
=head2 Attach/detach debugger from running program
debugger on a running Perl program, although I'm not sure how it would be
done." ssh and screen do this with named pipes in /tmp. Maybe we can too.
-=head2 inlining autoloaded constants
-
-Currently the optimiser can inline constants when expressed as subroutines
-with prototype ($) that return a constant. Likewise, many packages wrapping
-C libraries export lots of constants as subroutines which are AUTOLOADed on
-demand. However, these have no prototypes, so can't be seen as constants by
-the optimiser. Some way of cheaply (low syntax, low memory overhead) to the
-perl compiler that a name is a constant would be great, so that it knows to
-call the AUTOLOAD routine at compile time, and then inline the constant.
-
=head2 Constant folding
The peephole optimiser should trap errors during constant folding, and give
The old perltodo notes "Look at the "reification" code in C<av.c>".
-=head2 switch ops
-
-The old perltodo notes "Although we have C<Switch.pm> in core, Larry points to
-the dormant C<nswitch> and C<cswitch> ops in F<pp.c>; using these opcodes would
-be much faster."
-
=head2 What hooks would assertions need?
Assertions are in the core, and work. However, assertions needed to be added
