This is not a complete upstreaming of that file (it also supports `∀ᵉ (x < 2) (y < 3), p x y` as shorthand for `∀ x < 2, ∀ y < 3, p x y`, but I don't think we need this; it is used in Mathlib). Syntaxes still need to be made built-in. --------- Co-authored-by: Leonardo de Moura <leomoura@amazon.com>
