Namespace does NOT solve the problem. If MSE units uses M.<unit> for their units and you have yours the same as well, you'll end up renaming either anyway.

Yes and how I still use D7 at work I still have this problem.
This problem happen not only for unit names but component names too. I
can not register two components with the same name.
So, because that, programmers around the world use prefix in class
names. If the components were registered using 'unit+class_name' and
when we drop a component on the Form the IDE write the unit name as a
prefix, this problem not will happen.

My more fresh example is:
I have, for years, many units that have the prefix 'M'. So I have
MClasses, MCore, MTasks, MSystem, etc.
Now MSEgui (by Martin Schreiber) introduced a mclasses unit -- your
own implementation of classes unit -- and I can not use both units in

Sorry, I didn't understand what you mean. :(
