I know that **Naming is CRITICAL** and that **Refactoring only NOT welcome**.
But since I spotted this (consistent) typo and the change does not affect any
functionality -- I checked the presence of "asscoiated" in the code base, I
guess the first rule trumps the second one.
It also gave me a false pretext to bypass my reluctance to use Google forms and
sign de CLA. Typos hurt the eye.
