Specified input

[kjjeong104]

Hello,

As a follow-up for the issue for specification of variable type for a custom function,
trevorstephens#175

Have you figured out how to do that?
For example : I would like to add a pow(x,n)=x**n function such that the base is taken from array, but the second arity, power, is only accepted as integers.
The official version doesn't support it yet as we know, but do you have any idea that you succeeded to implement?

Sorry to reply in the new year.
I have modified the package a little bit and offer a new API to accept function set whose last input could be an integer. But I do it in a way through pruning the _program.

I would like to check if there's any progress on this issue？my thinking is to break mutation steps into 2 parts, first to mutate every constant params, then to imply custom functions without constant params as normal.
