How can we make it easier to experiment with the compiler?

I knew someone would bring that up. :-) It's a good question.

`core` is a separate library in its own, independent hierarchy, it is not in the 
`std` hierarchy. It is not "up sideways and down". So it's good.

Now, if std.stdio imported core.stdc.stdio, and core.stdc.stdio imported 
std.stdio, then you've got a really bad design.
