excuse me, but can someone explain what problem the pattern / workaround
is supposed to fix, does it create and return a default annotation value
in case an annotation key does not exist? shouldn't the annotation
machinery be "fixed" instead to provide getAnnotation(..., default=...) ?
I thought I described it in my initial post.
I was looking for a way to register annotations for objects (and create
them if they aren't there yet) without having to write fairly long bits
of code for each annotation factory.
I just want to be able to say:
myannotation = IFoo(obj)
where IFoo is the interface of an annotation of the obj. The only place
I worry about it being an annotation is in the registration code. No
need to import anything else from that package. Whether it needs to
create a new annotation or get an existing one is an implementation detail.

Martijn
