Смотрю, F# плюс продолжают активно пилить!!1

F#+ builds upon FSharp, using generic programming techniques to help you avoid boiler plate code.

Generic Functions and Operators like map, which can be extended to support other types
Generic and customizable Computation Expressions, like monad
A generic Math Module
Generic methods that help you with parsing
Some new types that work well with the abstractions, such as NonEmptyList, DList and Validation
Abstractions that capture common FP patterns, such as the standard monads Cont, Reader, Writer, State and their Monad Transformers
A polymorphic Lenses/Optics to easily read and update parts of immutable data
