It also breaks old style varargs.

local f: function(x: number, s: string, string...): boolean
local g: function(x: number, s: string, ...: string): boolean

> tl check fn-vararg.tl
========================================
2 syntax errors:
fn-vararg.tl:1:51: '...' can only be last argument
fn-vararg.tl:2:53: '...' can only be last argument
