To me this is yet another consequence of the current state of art in
assumptions:

In [2]: u1 = Symbol('u', real=True)
In [3]: hash(u0)

There was a similar error in the printing when I tried removing the
automatic distribution 2*(x + y) = 2*x + 2*y. I don't know if it's
related.

I don't think so. We do have expr.is_rational_function() and
expr.is_polynomial(), which are similar, though.

@Aaron: why simplify=False for eq5 in test_separable1? The first commented
out sol5 substitutes to zero and dsolve() can do it fast without
simplify=False.

OK. One more question: in test_separable2 now I get:
In [1]: eq7 = f(x)**2 - 1 - (2*f(x) + x*f(x))*f(x).diff(x)
In [2]: dsolve(eq7, f(x), hint='separable')
