+Checks if collection can be blank-compacted with `compact_blank`.
+
+=== Safety
+
+It is unsafe by default because false positives may occur in the
+blank check of block arguments to the receiver object.
+
+For example, `[[1, 2], [3, nil]].reject { |first, second| second.blank? }` and
+`[[1, 2], [3, nil]].compact_blank` are not compatible. The same is true for `empty?`.
+This will work fine when the receiver is a hash object.
+
+=== Examples
+
+[source,ruby]
+----
+# bad
+collection.reject(&:blank?)
+collection.reject(&:empty?)
+collection.reject { |_k, v| v.blank? }
+collection.reject { |_k, v| v.empty? }

+Since Rails 5.0 the default for `belongs_to` is `optional: false`
+unless `config.active_record.belongs_to_required_by_default` is

+automatically, and explicit presence validation is redundant.
