#filter_map ⇒ Object

NOTE: This is a backport of Ruby 2.7 filter_map. This method can be deleted when the minimum target Ruby version is 2.7 We’re not gating against redefining the method (e.g. via ‘unless Enumerable.method_defined? :filter_map`) because this would reduce the code coverage when analysing code coverage on Ruby versions >= 2.7
