>>> M = Matrix()
>>> v = Vector()
>>> M * v
Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
TypeError: Element-wise multiplication: not supported between 'Matrix' and 'Vector' types

>>> v * v
Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
