Rails/CompactBlank cop gets triggered by reject that calls blank? on unrelated object

[chrkau]

Consider the following code snippet:

def foo(bar = nil)
  [1].reject { |_| bar.blank? }
end

As far as I can see reject cannot be replaced with compact_blank here as the rejection condition relates to a different object (bar).
