getfenv disables LUAU optimizations why bruh? and what do i use bruh

so bro since getfenv disables some luau optimizations im wondering whats a way to replace it

so like im using it to inject variables from a module script into the requiring script like

local import = require(_M)

import "string.join"; -- the module script injects into getfenv(2), aka the calling environment

print(join("bruh", ".")) -- b.r.u.h

it injects a variable into the environment but since roblox super dum dum have, u simply cant use getfenv without losing optimizations

• why in the hell does getfenv disable them in the first place WHY BRO
• out of all the functions there are it had to be getfenv LIKE ANY FUNCTIONS BRO. why getfenv. nobody cares about setfenv
