Functions

func Compose

func Compose[T any](f, g func(s T) T) func(s T) T

f after g

func ComposeAll

func ComposeAll[T any](fs []func(s T) T) func(s T) T

g after f in order of fs

func Partial1

func Partial1[T1, T2, T3 any](f func(T1, T2) T3, s1 T1) func(T2) T3

Takes a function of two arguments and turns it into a function with one argument with the first argument bound. This is useful replacement for a Class with instance variables in OOP.

func Partial2

func Partial2[T1, T2, T3, T4 any](f func(T1, T2, T3) T4, s1 T1) func(T2, T3) T4

Takes a function of three arguments and turns it into a function with two arguments with the first argument bound. This is useful replacement for a Class with instance variables in OOP. TODO I wonder if there is a way to make the function variadic and still preserve generic type safety? I don't think so because type parameters cannot be variadic.
