This is the way its supposed to work. Each mixin gets its own namespace, so
that names can match names in the non-mixin declarations and other mixin
declarations. You can access those conflicting names by using the mixin name as
a scope operator.

Probably below cite would be more appropriate to describe why my bug was 
invalid:  :-))  (I don't know any way to access anonymous mixin members 
- if there is a way to do it I would be happy to know how...)

Mixin Scope
The declarations in a mixin are 'imported' into the surrounding scope. 
If the name of a declaration in a mixin is the same as a declaration in 
the surrounding scope, the surrounding declaration overrides the mixin one.

Sorry about invalid bug report. Something strange is happening with 
mixins in my program, so I thought that it was reason. But it must be 
something else. I will try to find it out and report in another bug report.
