Update 471 shows syntax for generic varargs as
function f<a…>(…: a…) end

And update 469 shows typed varargs as
function foo(…: T): …T

Which one is it? T… for generics and …number for builtin types? Or …number / …T for generics and the latest update is a typo?

EDIT:
3 weeks ago it said generics for functions were added, but I still can’t use them, any word on when they will be enabled?

Both!

function foo(...: number): ...number means it’s a function that accepts a variadic length of numbers.

function foo<T...>(...: T...): T... will mean that it’s a function that remembers every types of each values passed into ..., so you could write local a, b = foo(1, "hello") and we’ll know to return (number, string) in this case.

They’ll be enabled sometimes soon in the next week. Had to be disabled due to a critical issue, will be back in a few weeks. Type checking - Luau

Fixed a Luau compatibility bug with userdata comparison; userdata objects now always compare equal to each other since __eq calls are not performed on the object and itself.

In light of the fact that this bug became a feature we’re reevaluating this and the fix is likely to not get enabled.
