class RuboCop::Cop::Lint::SafeNavigationWithEmpty
This cop checks to make sure safe navigation isn't used with `empty?` in a conditional.
While the safe navigation operator is generally a good idea, when checking `foo&.empty?` in a conditional, `foo` being `nil` will actually do the opposite of what the author intends.
@example
# bad return if foo&.empty? return unless foo&.empty? # good return if foo && foo.empty? return unless foo && foo.empty?
