Will Coffeescript ever use optional types similar to Typescript?

Question

With the recent advent of Typescript and the optional static typing that he claims, Coffeescript developers most likely lack these features

Is Coffeescript capable and / or likely to accept optional types in future versions and how will the syntax work?

Answer 1

There is a fork for this Contracts.coffee .
