since then we had significant changes to Famix (this is why Jannik asked for a 4.0 release) that left things in an unstable state. Problem lies somewhere in underestimating the impact of the changes to Famix. It should probably have been considered a development version so that it is clearer what one was dealing with.
The issue is like I mentioned before: The Cook API is broken and needs revision. The larger problem is that we do not have tests that capture the problems.
Maybe we should consider retiring Moose Cook and migrating to Moose Chef?
