Lots of errors so far, working on fixing them. One problem is that the order of constructing units/quantities needs to be taken into account. Not sure what we can do...

it's still available, but some constructed units are now suddenly quantities. Leads to errors like this: ```python In [4]: (constants.Rydberg_constant * constants.h * constants.c) ...: ...: --------------------------------------------------------------------------- AttributeError Traceback (most...

Yes, the ror is untouched and still works. > maybe is also good to take stock of all the implications that this change has (issue?): > old simulation scipts >...

Another issue: 1.0 * unit will return the unit. This should probably return a quantity instead (in line with previous behaviour and other unit systems)

ah, of course that would be `__rmul__`...

This also fails: ```python In [31]: 2.0 * 2.0 * kg * m**2 Out[31]: quantity In [32]: 2.0 * 2.0 * kg**2 * m**2 --------------------------------------------------------------------------- AttributeError Traceback (most recent call...

it's really tricky...
