Module names are kinda unwieldy (e.g., one function call looks like this Spirit.Exercises.BinariesStringsAndCharlists.describe_string(s)). So, I suggest we update our structure to mitigate this by replacing the directory name from exercises to just spirit. I've shown it in detail below to make it clear.

Directory structure:

• Before: lib/exercises/binaries_strings_and_charlists.ex
• After: lib/spirit/binaries_strings_and_charlists.ex

Module name:

• Before: Spirit.Exercises.BinariesStringsAndCharlists
• After: Spirit.BinariesStringsAndCharlists

An added bonus is that this structure is probably more idiomatic since LSP completion now detects the module name correctly when I use the defmodule snippet.
