Which is why the original releaser<> proposal is not in the standard.
There are just too many different kinds of resource, with too many
different ways of acquiring and releasing them.  So it wasn't clear
that any general facility could improve on just wrapping each resource
in a class with constructors that acquire the resource and a destructor
that releases it.
