Right. But this is still inconsistent both with variant's get<> and e.g.
static_cast<>. The static_cast<> behaviour can't be done in current C++
(since you can't partially specialise function templates), so maybe variant's
get<> should be changed?
Hmm, maybe I lied when I said static_cast<> syntax is not possible... Lemme
try. This should give static_cast<> semantics for any_cast (ie. <T> cast by
value, <T&> by reference, and <T*> by pointer).
Hmm, the attached stuff works, but how would const char* work in this
setting...?
