Type safe pipe operator equivalent

pipeable.ts

class Pipeable<I> {
    constructor(public value: I) { }

    public pipe<O>(fn: (input: I) => O) {
        const output = fn(this.value);
        return Object.assign(new Pipeable(output).pipe, {
            value: output
        });
    }
}

export function pipe<T>(input: T) {
    return new Pipeable(input).pipe
}

usage.ts

const result = pipe(2)
    (v => v * v)
    (v => v.toString())
    (v => v.toUpperCase())
    .value // result is now string
