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.
