I often say to my cat 'what are you doing' .. but what i really 
mean is 'don't do that'.

by avoiding negation, I'm probably just confusing my cat as to 
what i really meant.

mustuse -> I must use it? Why must i use it? How must I use it? 
What happens if
i don't use it.

nodiscard -> don't discard it. nice and simple (just like 'don't 
do that').
