Aware of msgspec' Struct

[ssweber]

(sorry about the edits, somehow I clicked save before doing anything)

I've been curious at how to speed up dataclasses, and wondered if the team was aware of msgspec's Struct.

The author has a few interesting benchmarks, so I'd thought I'd share (hopefully this isn't unwanted noise).

	import (μs)	create (μs)	equality (μs)	order (μs)
msgspec	9.92	0.09	0.02	0.03
standard classes	6.86	0.45	0.13	0.29
dataclasses	489.07	0.47	0.27	0.30
attrs	428.38	0.42	0.29	2.15
pydantic	371.52	4.84	10.56	N/A

	GC time (ms)	Memory Used (MiB)
standard class	80.46	211.66
standard class with slots	80.06	120.11
msgspec struct	13.96	120.11
msgspec struct with gc=False	1.07	104.85

Why closing?

I never understood this issue (not enough context). It doesn't feel like it's relevant to the main purpose of this repo (discussion about interpreter performance). I believe the author understood that.
