Comment (by robertwb):
Thanks, Mike, for revewing this.
Replying to [comment:5 jhpalmieri]:
> Robert: after your patch, regarding `__mul__` and `_mul_` for matrices
in `element.pyx`: what are their roles? In what order do they get called?
To close the loop on this, `a.__mul__(b)` is called by Python when a * b
is encountered. `a._mul_(b)` is called by the coercion model when
`parent(a) is parent(b)` to actually do the arithmetic. Full details at
