Replying to [comment:75 bgillespie]:
> Note that `floor` and `ceiling` take multiple different types of
parameters, not just functions. This code checks for the type of the
input parameter and optimizes when using a constant or a list of integers.
Agree. However, with your code there is absolutely no way to specify
"`floor` is a function which is always at least 1". I should be able to
specify such an input with `floor=myfunc, min_part=1` and the code can
optimize this case better than when just specifying the function.
