[TYPO3-mvc] Proposal: mixed-ins for extbase

Yeah, in FLOW3, this is very easily possible. With AOP you can just
declare additional methods and properties of classes (or bundles of
classes), so that's an even more generic concept.

However, as a convenience feature, we planned to implement Mixins in
FLOW3 as well (with AOP): http://forge.typo3.org/issues/6712 .

In general, I think it is a nice and important feature, which would add
a lot to Extbase. However I fear that it is difficult to implement with
acceptable performance, but feel free to prove me wrong :-)

For the syntax of registering Mixins, I could imagine that we even use
the same syntax as FLOW3, but additionally, the class still needs to be
registered as mixin somewhere -- that way, mixins would be
forward-portable later on.

So, I look very much forward to example code :-)

Greets,
Sebastian
