Pattern: Use of case equality operator (===)
Issue: -
This rule checks for uses of the case equality operator (===). As its name implies it is meant to be used implicitly by case expressions and outside of them it yields confusing code.
# bad
Array === something
(1..100) === 7
/something/ === some_string
# good
something.is_a?(Array)
(1..100).include?(7)
some_string =~ /something/
