      AttributeError: 'Container' object has no attribute 'area'. Did you mean '.inner.area' instead of '.area'?
 
+* When an :exc:`AttributeError` on a builtin type has no close match via
+  Levenshtein distance, the error message now checks a static table of common
+  method names from other languages (JavaScript, Java, Ruby, C#) and suggests
+  the Python equivalent:
+
+  .. code-block:: pycon
+
+     >>> [1, 2, 3].push(4)
+     AttributeError: 'list' object has no attribute 'push'. Did you mean '.append'?
+
+     >>> 'hello'.toUpperCase()
+     AttributeError: 'str' object has no attribute 'toUpperCase'. Did you mean '.upper'?
+
+  When the Python equivalent is a language construct rather than a method,
+  the hint describes the construct directly:
+
+  .. code-block:: pycon
+
+     >>> {}.put("a", 1)
+     AttributeError: 'dict' object has no attribute 'put'. Use dict[key] = value for item assignment
