I believe that's what kinke is proposing too?

In C++, objects that are moved from should be left in an 
unspecified but
valid state. It is up to the move constructor to guarantee that 
rule is actually satisfied.

As I understand it, because we generally try to avoid the C++ 
of only guaranteeing things by ... convention, it could make 
sense to
reset moved-from lvalues to `T.init` implicitly.
