Support of higher order FRP?

[nikhedonia]

Could you elaborate which design goals you have when rewriting your library?
Are you only planning to support static computation graphs or are you considering higher order of FRP?

For instance, are you considering implementing operators over Observer<Observer<T>> ?
There are many use cases but supporting those are not for free.

EDIT:
Just noticed that the last commit was a year ago. Any (design) specific roadblocks ?
