Pyspread – Spreadsheet implementation in Python, cells return Python objects

I like the idea of using objects in cells - "Each cell returns a Python object". Any idea of the learning curve, how do users get on. How long does it take to learn compared to learning say vlookup?

Returning an object would help solve many spreadsheet problems. It is a great idea. Any thoughts on how to make the implementation easy to learn?
