Hi all,

ok then, i think a have to lift the curtain on what i did with SalesPoint & 
Co. ;)

Well, actually, SalesPoint and SalesPoint are two different types in two 
different packages. The first one obviously is an interface, but the second 
one is a class. [No comments please! This was just a snapshot during 
refactoring ;) ]

The idea behind that was to have a role class that implements a specific 
interface and is bound to a base class. The interface is required by 
some "legacy" component (outgoing interface of that component), and the base 
class is a class within another component. The team was meant to merely act 
as a "binder" (ADL-like).

This is, as mentioned above, not correct. The problem here was missing 
context-sensitive support due to AST analysis errors. Thus, i missed to fix 
the imports. :(

Anyway:

I actually do see cases where this would fit perfectly. Given that you have to 
refactor or even extend an existing code base w/o refactoring it, it might be 
useful to have such a mechanism instead of having to write an appropriate 
role class for _every_ base class one have to bind to.

That would be great. :)


Many thanks + kind regards,
Ralf
