Comment (by darij):
OK, I guess I don't understand the inner workings of `__mul__` and
`__rmul__`. Could you explain them to me?
If the Modules *category* is suited for nonsymmetric bimodules (without
having to manually override certain non-abstract methods in every
subcategory), then my edit on that file indeed should be reverted; thanks
for spotting that. But there still should be warning signs around this
class that it really allows for bimodules. And I fear that the dispatching
of Modules(field) to VectorSpaces(field) is strictly speaking incorrect in
this case.
