PureScript: using newtype with records

I ran into a beginner mistake that I was unable to figure out. So I posted to PureScript Discord and the conversation quickly showed me not only why what I did didn't work, but suggestions for how to fix it specifically. Kudos to @monoidmusician and @natefabion. Here's the discussion:

I have a compiler error that I'm just not understanding why it's happening: Here's the test code:

module Foo where

Introduction

This exercise shouldn't have been that challenging, but it stumped me. Here's my woeful journey with the path through it so that I can review my approach when I get stuck on the next exercise.

The Exercise

Found in the Purescript Book, exercise 2:

(Medium) Write a function possibleSums which uses foldM to determine all possible totals that could be made using a set of coins. The coins will be specified as an array which contains the value of each coin. Your function should have the following result: >

Here's the code as part of a coding exercise (the 2nd one) here:

module CartesianProductExercise where
  
import Prelude

import Data.Tuple (Tuple(..))

Multiple MySQL Versions with Homebrew

NOTE: this is me experimenting w/ more recent versions. This isn't working yet.

For homebrew version 1.3.0.

brew -v # => Homebrew 1.3.0

Install the current version of mysql.

Organization

web only has code that has no state. Changes to these files auto- restarts the server.
lib functionality manages state. (Note: server does not auto-reload w/ changes to these.

What is above is a property of :reloadable_paths.

TL;DR

Write code for other programmers, not machines.
Code should represent the best understanding of the programmer when he writes it.

Here's the original:

require 'spec_helper'

feature "A user signing up for a beta invitation" do
  scenario "with valid parameters" do
    visit '/'
    fill_in "Name", with: "John Doe"
    fill_in "Email", with: "[email protected]"

Driving Instructions to Orphanage from Dianne's House

These instructions can be accessed two ways:

As a paper handout; see Dianne.
As a PDF file in your smart phone. The iPhone, for one, has iBooks which can hold a PDF file in your smart phone's memory and access it. Once loaded, you don't have to have a live Internet connection; this is handy when you want to turn off access in México to avoid (expensive!) roaming charges.
