High-scores has high cognitive load for new Lua users (mentoring feedback)

[glennj]

High-Scores is quite early in the list of exercises. It's probably the first one to introduce colon notation and the idea of a function returning a table with functions. I've had a few mentoring sessions where the user was pretty lost.

I don't have any concrete suggestions at the moment. Some thoughts:

• add an introduction.md.append file to discuss:
  • closures and/or OOP in Lua
  • return values from modules
  • colon notation versus dot notation
• flesh out the stub file a bit
• move the exercise later in the list of exercises and/or bump the difficulty

Thanks for the feedback. I'll flesh out the stub, bump the difficulty, and move it so that it comes after Binary Search.
