Abuse Golang library

What?

package main

import (
 "fmt"

 "github.com/pidpawel/abuse"
)

func main() {
 result, exception := (&abuse.PromiseSlice[int]{
  abuse.New(func() int {
   return 1
  }),
  abuse.New(func() int {
   return 2
  }),
  abuse.New(func() int {
   return 3
  }),
 }).ForEach(func(arg int) int {
  return 10 + arg
 }).Fold(0, func(a, b int) int {
  return a + b
 }).Await()

 if exception != nil {
  panic(exception)
 }

 fmt.Println(result) // Should be 11 + 12 + 13 = 36
}

How?

Generics. They're both a blessing, a curse and a mean to an end of this language. (This is not a place for such debate but tldr: they're powerful enough to enable people to port multiple concepts from other languages that may stand against core values of Go.)

Also goroutines and no reflection. That, unfortunately, doesn't mean that it will be blazing fast tough. Should be OK for IO/networking but awful for quick and dirty local patchups.

Why?

Oh boy. I've stumbled upon lo, mo and promise while I was sick during time off and it seemed like a fitting way of spending an evening.

Install

Don't.

Seriously though I'd be glad if someone used my work, but this particular piece seems to me more like a cheap way of achieveing a complicated result disregarding all the powerful tools that Go provides. If you find it fitting for your project despite this - sure, give it a go but remember that most likely one day you'll have to pay that technical debt.
