I myself *very* need SymPy to be faster. For example it takes me a lot
of time to just wait for tests passing.

I do not think separating sympy.core into its own project is a good idea.

The reason is that not only core affects everything else, but everything
else also affects core and it's design. So having both core and
'high-level' stuff in one place will help to improve *both*.

I agree that structuring things is good, but we are already on that
road, right?

I think what we really need to be able to experiment easily is a more
distributed development model. This could be slightly ooftopic, but an
