Pattern: Redundant equality comparison block
Issue: -
Checks if Enumerable#all?, Enumerable#any?, Enumerable#one?, and Enumerable#none? are compared with === or similar methods in block.
By default, Object#=== behaves the same as Object#==, but this behavior is appropriately overridden in subclass. For example, Range#=== returns true when argument is within the range. Therefore, It is marked as unsafe by default because === and == do not always behave the same.
# bad
items.all? { |item| pattern === item }
items.all? { |item| item == other }
items.all? { |item| item.is_a?(Klass) }
items.all? { |item| item.kind_of?(Klass) }
# good
items.all?(pattern)
