It's mostly c) but it is sometimes difficult to distinguish these cases.
E.g. in my opinion shadowing a local with a new one with the same name
can be a source of bugs, but I've seen people consider warnings
about this annoying and stylistic. I try to make the warnings
clear-cut and provide options to ignore some of them according
to alternative preferences. It seems like overkill in this
particular case though.
