Would have benefited from blocked words of different lengths. That would have made the task ( ever so slightly ) more interesting.

There is this one test where the blocked word is not the entire word. Behaviour around that is completely unspecified. Most interesting option would probably be to require that only complete words are blocked. But specify such things, escpecially when one of the blocked words already is a plural!

Hi,

• well, it has been done already... :/
• it would need random tests
• you don't talk about the behavior with plurals in the description
• missing a lot of edge cases with false (?) matches: caller, codewars, ... => the behavior is undescribed: should they match or not (I feel like they shouldn't)

cheers
