@kytrinyx @ErikSchierboom Before I continue with the last bits of `Maybe` and then `Either` and tuples: what do you think of this style and depth?

The exercise is now visible to students, as is the accompanying concept. However, the syllabus is still hidden. Is this the preferred state?

The solution to Valentine's is feature-complete, so to speak. It matches on a custom ADT (`Activity`), matches on fields (e.g. `Korean`), uses binding patterns (not sure this is the right...

It occurs to me that `Maybe`, `Either`, tuples, … do not actually depend on _**Simple Pattern Matching**_.

This is taking way longer than expected, and @pwadsworth is being productive in my absence, so I tried to write down my thoughts here below. # Pattern Matching & Data...
