Well, it opted for the default output for all pointer types. It's
hard to strike a balance with respect to which default functionality
can be overriden and which cannot. I guess it makes sense that the
metamethod should override the default output in this case.

So I've just made it that way in git HEAD. Your example works now
as expected.

No such problem here. Either you've messed up your VC++ installation
(installed extra headers?) or you have a broken git tree. Consider
pulling a fresh copy and try again.
