I am sure we can but in the end, `test_numerically` just uses the `comp` function:
https://github.com/sympy/sympy/blob/master/sympy/utilities/randtest.py#L64

So, if we do this, it'll just require more function calls inside the `test_numerically` function.
Anyway, if you guys want to see this changed to `test_numerically`, let me know.
