It much easier to solve then that, just make a,b,c globals in the class
constructor (again, let's consider than objects, not primitives.) If
you look at my stuff, you'll see it's pretty free from GC, but that's
because I pull a lot of tricks, which make for messy and hard to
understand code.
The point is to find a way to do this without convoluted stuff that ends
up making brittle or spaghetti code -- and is subject to sudden changes
if someday an engine decides to do GC in a different way, being clever
could suddenly turn against you.

I think the original problem that caused this discussion with GC could
be solved with just a weak map:
```
// Original
class thing {
doSomething(x, y) {
let a = x + y;
let b = ay;
let c = bx;
return (c);
}
}
// With a weak map
const wm = new WeakMap()
class thing {
doSomething(x, y) {
let data = wm.get(this)
if (data === undefined) {
wm.set(this, data = {
a: x + y,
b: ay,
c: bx,
})
}
return data.c;
}
}

But we want to stay in JavaScript because we like the language.
Plus, writing a framework in JavaScript has the obvious advantage
that a beginner web programmer can just start using it
easily (HTML/JAvaScript is like the gateway drug of programming
nowadays so there's certain advantages to writing a library in JS
as opposed to in C or compiling to WebAssembly).
I don’t think there being an alternate is any reason to not improve
something. I’m realistic here, I know there are concerns which are
1,000,000x more important than me, games or other time sensitive
applications, and backwards compatibility and language complications
and sometimes philosophy. Just a few things here and there, though,
not necessarily any of the ideas I’ve come up with, can solve or
mitigate this problem.
I never thought I’d see modules or classes! Everything is on the
right path. Just being able to deal with the GC (and maybe types if
I’m lucky) is the only big hurdle to the kind of thing myself and
others are doing.
