This issue was originally filed by @decitrig

Currently the spec forbids typedefs such as the following:

typedef StateFn StateFn()

Where this would mean a function that returns another function of the same type. It would be nice to be able to define such functions, as right now they just have to be defined to return Function and the type information is lost.

The type system people get this alarmed look on their face any time recursive types come up. We haven't seen any motivating uses for this, so, in the absence of that, we'd rather keep things simpler.
