=head2 The Internals Phase

1999-2000 were disastrous years for me personally but magnificent years
Perl-sonally. Stuck in a boring job and a tiny flat in the middle of
Tokyo, I had plenty of time to get stuck into more Perl development. I
felt that getting involved with C<perl5-porters> would be a good way of
gettting to know more about Perl, and so I needed a hobby horse - an
issue of Perl's development that I cared about. Since I was in Japan and
working a lot with non-Latin text, Unicode support seemed a good thing
to work on, and so L<Unicode::Decompose> appeared, while I fixed up a
substantial part of the post-5.6 core Unicode support.

I'd recommend this way to anyone who wants to get more involved in the
Perl community, although I was very lucky in terms of who else happened
to be around at the time: Gurusamy Sarathy was extremely gracious in
helping me turn my fledgling C code into something fit for the Perl
core, and he also helped me understand the C<perl5-porters> etiquette
(yes, there was some at the time) and what makes a good patch, while
Jarkko Hietaniemi was always good for suggestions of interesting things
for keen people to work on. Seriously, get involved. If I can do it,
anyone can.

=head2 Messing About With Classes

One of the things that continues to amaze me about Perl is its
flexibility; the way you can change core parts of its operation, even
from pure Perl. This lead to quite a few modules, many of which were
mere proofs of concept.

L<Sub::Versive>, for instance, was the first module on CPAN to handle
pre- and post-hooks for a subroutine; it has since been joined by a
plethora of imitators. It was written, though, in response to a peculiar
scenario. I was writing a module (C<Safety::First>) which provided
additional built-in-like functions for Perl to encourage and facilitate
defensive programming and intelligible error reporting. ("Couldn't open
file? Why not?") These built-ins had to be available from every
package, which meant playing with C<UNIVERSAL::AUTOLOAD>. But what if
another package was already using C<UNIVERSAL::AUTOLOAD>? Hence,
C<Sub::Versive> wrapped it in a pre-hook. Of course, with the
interesting bit of the problem solved, C<Safety::First> was abandoned.
