Going back to what was initially intended by nyxton in order to simply exercise.
Using simple tuple type makes it much easier to understand and makes more sense as it keeps it simple.
"Nesting" tuples makes it unusual and somehow complicated.
After being stuck on exercise enums3.rs for about an hour or two, having read the entire chapter on enums 2-3 times, and still being unable to complete the exercise, i started broadening my reading. I finally found the answer in the rust docs via google.
Hints are now accessible using the CLI subcommand `rustlings hint
<exercise name`.
BREAKING CHANGE: This fundamentally changes the way people interact with exercises.
