I think the largest hurdle I have getting running with maybe, is that it just isn't in my fingers yet. As such, it can really slow you down if you were trying to build a bare bones prototype without layering. Which, given the popularity of dynamic languages, I would think is fairly common.

That is, if you are going to use Maybe, you either want to do so from the beginning, or you want a good layer of abstraction between where the value is optional and where it is not. Moving something from guaranteed to optional is a bit more combersome with Maybe.

Also, I have gotten really used to "truthy" values.
