+=head2 Parallel testing
+
+The core regression test suite is getting ever more comprehensive, which has
+the side effect that it takes longer to run. This isn't so good. Investigate
+whether it would be feasible to give the harness script the B<option> of
+running sets of tests in parallel. This would be useful for tests in
+F<t/op/*.t> and F<t/uni/*.t> and maybe some sets of tests in F<lib/>.

+How do setup/teardown tests identify themselves?

=head2 Make Schwern poorer
We should have for everything. When all the core's modules are tested,
various times worked to cut it down. There is probably still fat to cut out -
for example POSIX passes Exporter some very memory hungry data structures.
-=head2 Refactor C<xsubpp> to be a thin wrapper around C<ExtUtils::ParseXS>
-
-C<ExtUtils::ParseXS> encapsulates a version of the C<xsubpp> into a module.
-In effect this is a code fork, and it's likely that C<xsubpp> has had some
-bug fixes since the code from C<ExtUtils::ParseXS> was derived. It would be
-good to merge the differences in, reduce down to 1 canonical implementation,
-and convert C<xsubpp> to a very thin command line wrapper to
-C<ExtUtils::ParseXS>.
-
-In theory this needs no real C knowledge, as one way of approaching this task
-is to ensure that C<ExtUtils::ParseXS> generates identical output to C<xsubpp>
-for input XS files, which does not require understanding the contents of the
-output C file. However, some C knowledge is likely to help with testing, and
-locating/producing comprehensive test cases.
It would be good if someone were able to track down the causes of these
problems, so that parallel builds worked properly.
+=head2 linker specification files
+
+Some platforms mandate that you provide a list of a shared library's external
+symbols to the linker, so the core already has the infrastructure in place to
+do this for generating shared perl libraries. My understanding is that the
+GNU toolchain can accept an optional linker specification file, and restrict
+visibility just to symbols declared in that file. It would be good to extend
+F<makedef.pl> to support this format, and to provide a means within
+C<Configure> to enable it. This would allow Unix users to test that the
+export list is correct, and to build a perl that does not pollute the global
+namespace with private symbols.
+
when making a tarball, yet leave the default source saying "I'm not the
official release".
+=head2 Tidy up global variables
+
+There's a note in F<intrpvar.h>
+
+ /* These two variables are needed to preserve 5.8.x bincompat because
+ we can't change function prototypes of two exported functions.
+ Probably should be taken out of blead soon, and relevant prototypes
+ changed. */
+
+So doing this, and removing any of the unused variables still present would
+be good.

F<thrdvar.h> and F<intrpvarh> define the "global" variables that need to be
Study the possibility of adding a new prototype character, C<_>, meaning

+=head2 state variables
+
+C<my $foo if 0;> is deprecated, and should be replaced with
+C<state $x = "initial value\n";> the syntax from Perl 6.

The second return value from a sub in @INC can be a source filter. This isn't

will be greatly appreciated.
