Thing that just bit me because #Perl is not quite dwimmy sometimes:
```
my $foo = pop split(/bla/, $str);
```
(can't pop scalar in modern Perl and this construct puts split into scalar context I guess and that's not fun for pop)
(wanted to avoid the ugly `(...)[-1]` construct)
Updated my crusty but working #Perl module that computes "barycentric musical interval space."
"What?" you may ask... Good question!
"[The monograph] presents a novel approach to music theory by representing chords as points within a geometric 'simplicial grid,' based on their internal interval structures rather than pitch classes." Whew.

A New Geometry of Musical Chords in Interval Representation: Dissonance, Enrichment, Degeneracy and Complementation
This monograph covers a fresh and original look at musical chords. The idea emanates from the fact that an intervallic representation of the chord leads naturally to a discrete barycentric condition.iUniverse

A new blog post on the nature of #CPAN-based experiments at adding new syntax and features to the #Perl language.
Or at least, the first half before I get around to writing the thing I was actually going to say, in likely a follow-up post next week.

Today I have decided to bump the minimum #Perl version requirement of Object::Pad up from 5.18 (released in summer of 2013), to 5.22 (released in summer of 2015). This has allowed me to remove quite a lot of ifdef-guarded code, as well as plenty of workarounds for missing things (the UNOP_AUX and PADNAME types) in those older perl versions.
This sort of spring cleaning is useful to do every once in a while.

Shout out of appreciation for the #Perl module Test::LWP::UserAgent.
It allows one to create a wrapper UA to test code that uses an API module for a third-party API by faking the responses to some API calls.
It's been really useful for a project.

Revisiting a topic I haven't written about in a while, integrating #midi library RtMidi's event loop with other #Perl event loops.
The previous approach relied on a forked process (routine) which did little else but send back MIDI bytes via a channel, plus it only targeted IO::Async.
The approach described here should be simpler and more flexible, even if it does mean I had to write C. (I used to be paid to write C - this should terrify you).
@PerlFFI made this easy!

During my recent debugging of a `Future`-related memory leak issue, I had occasion to swap a program from using `Future::XS`, to the pure-perl `Future::PP` implementation instead.
As the program runs a very flat stable CPU load, such a change made it easy to see the performance different such a change made.

Marlin Racing
When I first introduced Marlin, it seemed the only OO framework which could beat its constructor in speed was the one generated by the new Perl core class keyword. Which seems fair, as that’s implemented in C and is tightly integrated with the Perl interpreter. However, I’m pleased to say that Marlin’s constructors are now faster.

It seems my #Perl memory leak issue is ongoing. While I managed to fix one big one, it turns out there's still a *slight* heap growth ongoing:
This time I'm going to post about debugging it in real-time, so this will be more of a story of exploration.
It starts with a monitoring graph, in which I noticed still a slight upwards trend. I restarted the process in the middle here with some extra debug modules loaded.
It used to have a memory leak. Now it doesn't.
Fixed by the help of `Net::Prometheus` and extended #Perl heap monitoring metrics.

I have decided that any new releases of existing #CPAN modules that I make will now be bumped up to needing at least perl 5.20 (except in a few odd cases).
This means they can now all use a bunch more new features such as signatures. The benefits purely on line-count, readability, and the basic argument checking that it gives, already seem worth it.
Already any new dists I make tend to be 5.36+ or 5.38+ if using `class`; but this now applies to existing ones as well
