Okay I've found a problem.
Here is some code demonstrating it.

Now take a look again at Database
https://github.com/cruisercoder/dstddb/blob/master/src/std/database/poly/database.d#L37
Do you see the problem?
The solution is simple.
The client database type can be a struct or a class. It doesn't matter
too much (assuming you're going the way of ranges).
But the intermediary representation must be on the heap and should
probably use the constructor and not a static create method to get it.
This way people can use other memory management solutions and construct
it however they like.
