Twisting Pool Queue

by Leonard Ritter leonard.ritter@duangle.com, 2019-05-12

An implementation written in Scopes can be found here

We have the task of distributing IDs to objects in a pool that we can use to look up their contents. We want to ensure that:

  • Insert, access, and remove are operations with O(1) complexity.
  • The object array is compact, i.e. without any gaps, so we can parallelize work on it with full occupancy.

Introduction

I was recently asked to explain why I felt disappointed by Haskell, as a language. And, well. Crucified for crucified, I might as well criticise Haskell publicly.

First though, I need to make it explicit that I claim no particular skill with the language - I will in fact vehemently (and convincingly!) argue that I'm a terrible Haskell programmer. And what I'm about to explain is not meant as The Truth, but my current understanding, potentially flawed, incomplete, or flat out incorrect. I welcome any attempt at proving me wrong, because when I dislike something that so many clever people worship, it's usually because I missed an important detail.

Another important point is that this is not meant to convey the idea that Haskell is a bad language. I do feel, however, that the vocal, and sometimes aggressive, reverence in which it's held might lead people to have unreasonable expectations. It certainly was my case, and the reason I'm writing this.

Type classes

I love the concept of type class
