The fundamental trait `is_constructible` reports false positives, e.g.

    is_constructible<char*, void*>::value

evaluates to true, even though a corresponding variable initialization would be ill-formed.

[ Resolved in Rapperswil by paper N3047. ]

Proposed resolution:

Remove all false positives from the domain of `is_constructible`.
