[Proposal]: add pipe utility function

[EhsanKey]

Function Signature

function pipe<T>(...fns: Array<(arg: T) => T>): (input: T) => T {}

Motivation

In functional programming, it’s common to apply multiple transformations to a value in sequence.

The pipe function allows us to write code more declaratively and clearly by chaining multiple functions from left to right:

const result = pipe(
  double,
  increment,
  square
)(2); // ((2 * 2) + 1)^2 = 25

This approach improves code readability and makes understanding function composition easier compared to nested calls like square(increment(double(2))).
