It shows bugs classified by "type". However, the type of many of the
bugs is "unknown". This greatly lowers the chances of them getting
fixed, as the number of open bugs is overwhelming -- too many to wade
problem. Such code should be added to the test suite as TODO tests, and
the ticket should be classified by type. To get started on this task,
look at the tickets that are marked as "New Issues" in
-L<https://rt.perl.org/rt3/NoAuth/perl5/Overview.html>.

=head2 Migrate t/ from custom TAP generation
quite a few tests in F<t/> have not been refactored to use it. Refactoring
any of these tests, one at a time, is a useful thing TODO.

On these systems, it might be the default compilation mode, and there
is currently no guarantee that passing no use64bitall option to the

none of the above (nor sprintf(), vsprintf(), or *SHUDDER* gets())
ever creep back to libperl.a.

Note, of course, that this will only tell whether B<your> platform
is using those naughty interfaces.

=head2 Virtualize operating system access
Implement a set of "vtables" that virtualizes operating system access
-(open(), mkdir(), unlink(), readdir(), getenv(), etc.) At the very
-least these interfaces should take SVs as "name" arguments instead of
-bare char pointers; probably the most flexible and extensible way
-would be for the Perl-facing interfaces to accept HVs. The system
-needs to be per-operating-system and per-file-system
-hookable/filterable, preferably both from XS and Perl level
-(L<perlport/"Files and Filesystems"> is good reading at this point,
-in fact, all of L<perlport> is.)

This has actually already been implemented (but only for Win32),
take a look at F<iperlsys.h> and F<win32/perlhost.h>. While all Win32
would produce this output
- Use of uninitialized value $undef in addition (+) at wrong.pl line 4.
- Use of uninitialized value $undef in addition (+) at wrong.pl line 7.
+ Use of uninitialized value $undef in addition (+) at wrong.pl line 4.
+ Use of uninitialized value $undef in addition (+) at wrong.pl line 7.
(rather than lines 4 and 5), but this would seem to require every OP to carry
(at least) line number information.
