New in ruby-2.7.0 filter_map


items.each_with_object([]) { |item, obj| obj << if }

This allows nils and falses.

I don’t like this filter_map thing as-is.

Couldn’t something like this be made to work:

items.filter_map do |item| next if end

With plain map next will give you a nil, but maybe it could be handled differently inside filter_map.
