I fully agree. I'm also in the "no use" clan.

Far better to declare the constant NO_ERROR and the packages SIEMENS_S5
and CRANE. Then CRANE_NO_ERROR or CRANE.NO_ERROR does not have more
characters and avoid to have a extended visibility.

I've never understood why people just put use everywhere and most often
at the top of the unit. This gives visibility to the whole unit plus all
the children. It is then harder to refactor the code as it is quite
difficult to see what is actually used and where.
