But sometimes that requires too much effort ;-)

e.g.

!debug { do this }

My brain decided this form of logic without me really thinking at 
all.

Now I have to 'rethink', in order to find the correct form of 
that logic that doesn't require the use of !

nodiscard is better than mustuse for the same reason.

Suppose I don't want to 'use it'. That should be allowed, as long 
as I don't discard it. With mustuse, I'm being told I can't 
discard it, and that i must use it.
