From 221edbae3843848047825701e25b6f9d8b096075 Mon Sep 17 00:00:00 2001
From: Niko Matsakis <niko@alum.mit.edu>
Date: Mon, 3 Nov 2014 21:52:52 -0500
Subject: Support parenthesized paths `Foo(A,B) -> C` that expand to
 `Foo<(A,B),C>`. These paths also bind anonymous regions (or will, once HRTB
 is fully working).

Fixes #18423.
