But if you have an integer array, you will run into the same problem.
The result will be upcast to float. I think we would accept a patch
that interprets None to be the appropriate extreme bound given the
input datatype. This will be tricky, though, since it must be done in
C (PyArray_Clip in numpy/core/src/multiarray/calculation.c).
