I was not able to fully follow this categorization, could you tell me under
which category is the following example?
https://pdimov.github.io/hash2/doc/html/hash2.html#example_md5sum

Those are the usecases which I was "targeting" with hard to misuse wrapper
since I presume:
- if library was successful those kind of uses will be most common
- knowledge of preconditions to use library of average end users is lower
on average than those of library implementers(here talking about both Hash2
library and some other library that uses Hash2 framework to add new hash).
