KSSU splits timer GUI challenge

This document presents an informal “GUI framework benchmark” along the lines of [TodoMVC][]: it is a relatively simple, well-defined problem that can be used to illustrate the strengths and weaknesses of different GUI paradigms. However, unlike TodoMVC, this problem is specifically designed to stress test state management in multi-stage modal flows, where modifications to the application state can be complex but must not be committed immediately.

The problem in question is to write a speedrunning timer for [Kirby Super Star Ultra][kssu]’s [True Arena boss rush mode][kssu-true-arena]. This is a completely meaningless problem to most people, but that’s okay—this document does not assume any familiarity with KSSU or with speedrunning timers more generally. However, I do want to go over a couple basics to provide some context on the problem being solved:

• The True Arena is a videogame boss rush mode where the objective is to beat a series of bosses as quickly as possible.

The Problem

Defining records in Haskell causes accessor functions for the record's fields to be defined. There is no seperate namespace for these accessor functions.

The Goal

Be able to

• use records in Haskell, which share field names.
• use lenses for accessing these fields
