While evaluating that a proposed hello-world exercise in #475 would
introduce Maybe into the track at the first exercise, I found myself
wondering what other exercises introduce Maybe. I decided to put this,
and select other topics, into the config.json file.

The topics selected are, largely, those that might affect a problem
ordering decision. They are topics that either require some effort to
grasp (so we should not put them too early) and/or are repetitive (so we
should not place them too close together).

  • Maybe
  • Either
  • Lazy evaluation
  • Define a data type
  • Library reimplementation
  • Refactoring
  • accumulator-strictness
  • instance TC (where TC is any typeclass other than Eq or Show)
  • IO Monad
    • Random
    • Mutable state

Closes #274.

These can't be the only topics that are important in this way. You could help by suggesting more.

I didn't check each topic against the exercises, but I bet everything is great.

Thanks for doing all the hard work, @petertseng!
