[libcxx-commits] [PATCH] D62454: SFINAE on pair/tuple assignment operators 2729

[Eric Fiselier via Phabricator via libcxx-commits]

EricWF added a comment.

We should already have tests for this.

And you should only write `fail.cpp` tests when there is absolutely no other way to test the behavior.
In this case it can be tested with a passing test and type traits.
