Feature Request: type safe function composition

There are many third party libraries, which aim to provide functional programming tools. Examples of this are fn.py and and funcy. They both provide a compose function that allows you to chain together an arbitrary number of functions. However none of the implementations are compatible with MyPy. Has there been any thought on the MyPy team about supporting such a feature, possibly in the typing submodule? I was able to get such a feature working with composing two functions, similar to this blog post https://www.fabianism.us/blog/2015/11/18/function-composition-with-types.html. But this doesn't scale to an arbitrary number of functions.

Inizia esaminando il sottomodulo typing e l'approccio a due funzioni descritto nel post del blog collegato. Definisci come la composizione di funzioni debba supportare un numero arbitrario di funzioni rimanendo compatibile con MyPy, quindi valida il comportamento con casi rappresentativi di controllo dei tipi.
