Why are compiler devs in such high demand for Julia?

Maybe it’s the natural consequence of wanting to use bleeding-edge stuff? They might not intend all users to use the latest version all the time, but some users want to anyway.

And Once across quickly over the top - e.g. some selected / excerpts / details inside gcutils.jl:

"""
	Base.GC

Module with garbage collection utilities.
"""
module GC

# mirrored from julia.h
const GC_AUTO = 0
const GC_FULL = 1
const GC_INCREMENTAL = 2

"""
	GC.gc([full=true])

Perform garbage collection. The argument `full` determines the kind of
collection: A full collection (default) sweeps all objects, which makes the
next GC scan much slower, while an incremental collection may only sweep
so-called young objects.

!!! WARNING
	Excessive use will likely lead to poor performance.

@jpsamaroo maybe for more deeply into the details,
IOW If someone REALLY wants to know , maybe try searching here for : gc correctness
BTW @Tarny_GG_Channie re “do something with linear algebra stuffs efficiently” I was surprised to find LinearAlgebra.tr (function, Linear Algebra) in the search results for : gc correctness (or is that actually just an LLM Search hallucination / confabulation? Let us know what you find out?)
