TL;DR: I cannot re-produce jnap's results.
Having read John Napiorkowski's
[post](https://dev.to/jjn1056/benchmarking-core-class-573c) benchmarking the
new class feature in 5.38.0, I didn't find his results too surprising. I
noticed however his script was a little naieve in places. Moose does a lot of
work during compilation to speed up runtime performance. Moo originally
detected if Moose is loaded and just provided a shim, it may still or it may
not. So I modified his script to isolate each run using string eval in a BEGIN
block.
I also set it up to use `time` on each run to compare the startup times of the
various runs and here are the results I got on my 13-inch, M1, 2020 MacBook Pro:
```

I also ran this on an Intel Macbook to see if that was the difference, on my

I also tried this on a fresh install of Ubuntu 22.04.3 LTS in an LXC container on an older Intel Xenon CPU:

```
I ran each run 3x on each box to make sure there wasn't any system caching or
something that was going to affect performance and all the runs were
comparable. You can see them for yourself below.
Finally I ran Jnap's original code to make sure my changes weren't the cause of these different results:
```
Moose: Create and access: 41 wallclock secs (42.17 usr + 0.04 sys = 42.21 CPU) @ 473821.37/s (n=20000000)

Moose size: 420 bytes
Moo size: 420 bytes
Core size: 107 bytes
Bless size: 120 bytes
```
SO while I fully believe John's results, I cannot reproduce them on any of my
machines. I'm seeing a distinct performance benefit to the class feature over
Moo and Moose but not as much as a bare bless.
