Typescript: Function composition and recurrent types

While I was working on our toolkit library Desmond I stumbled upon a problem when defining the TypeScript definition for a function pipe.

With help from Joe Calzaretta, a software developer working for MIT's IS&T, I defined type definitions for a variadic function composition in TypeScript, that is in some aspects superior to the existing solutions implemented in popular libraries.

Adapting the proposed solution I managed to define the HOC function type for composition without overloads, ultimately allowing it to safely type-check function chain for any number of arguments, which is a feature lacking in type definitions of even extremely popular utility libraries such as Lodash.

What is pipe?
