Exceeded allowed depth big & chain

[Boegie19]

I have a very & chain of
& (className: "Name") -> ((NameProperties) -> Name)
what Exceeded the allowed depth but if I split it up in 2 and then do
export type ClassNameConstructors = ClassNameConstructors0 & ClassNameConstructors1 it does not exceed the allowed depth and everything is fine.

both scripts are in this zip document
TestCases.zip

So I think luau should be able to handle big chains of &
and also why does the ClassNameConstructors0 & ClassNameConstructors1 work but just adding it in all big & chain not?

We have syntactic limits on all constructs - they exist by design. It's the same reason for why you can do this:

local a = 1 + 1 + ... (500 times) + 1
local b = 1 + 1 + ... (500 times) + 1
local c = a + b

but can not do this:

local c = 1 + 1 + ... (1000 times) + 1

Since our parser and many internal algorithms are recursive, this helps make sure that we use a limited amount of stack space in recursive algorithms.

We will double check whether the limits are required in this specific case though.
