Also regarding our brief talk in IRC, there are quite a few applications of Combinatorial Numbers[1][2] Apart from these could you suggest some more symbolic things which could added as a part of my proposal? After a quick check I could find the following additions which could be merged to my existing proposal, adding hyperbolic functions on the similar lines of current implementation of Trignometric Functions, or (a bit more ambitious) adding basic version of Taylor series expansion along the lines of SymPy. How do these additions sound?
