If you don't want it to point to a local variable and cause problems when it 
goes out of scope, then yeah, though I don't know if it's possible to do that 
or not. Probably, but I'd have to think about it and try out a bunch of stuff 
to be sure. Certainly, you could stick it in a struct and have a pointer to 
the struct.

Regardless, I would point out that you lose polymorphism if you do that. You 
only get polymorphism with references, not pointers. So, you don't want to try 
and call member functions on a class instance through a pointer.

But what you really should be using is std.typecons.Rebindable. If you're 
operating on pointers to class references much, then you're probably doing 
something wrong with your design. Classes really aren't intended to be used 
that way.
