[v3 PATCH] Avoid endless run-time recursion for copying single-element tuples where the element type is by-value constructible from any type

[Daniel Krügler]

Have you considered to test against decay instead of
remove_reference/remove_const? That would be similar to other places
in the standard. (I also believe that your fix actually should be
submitted as an LWG issue)
