Today I stumble upon

FAMIXPackage>>clientPackages
    ^ self inheritedByPackages union: self invokingPackages

which seems wrong because it does not take into account referencing packages. Checking
with Hani, it is self 
referencingPackages instead of self invokingPackages in VW. My guess is that the renaming
went wrong.

Could someone go through this one again?

Well I feel cold about this:
- for one thing, changing that requires checking that all updated call sites - tedious,
and I'm afraid we will lose time asking in some cases whether it makes sense to call
that or that
- for another thing, that's exactly why we undertook the MooseChef project with Jannik,
which aim at clarifying all this stuff and providing clear and simple semantics

In other words, it works fine for now, we may break things in unexpected way if we
change, and we plan to replace/rewrite it in 4.2 with MooseChef. So I would not make
it a requirement for 4.1

Ok. It's great to hear that MooseChef is scheduled for 4.2 :).

I marked the issue for 4.2

This should go away when MooseChef is integrated. I would close it for now.

Actually I'm thinking of marking it as invalid now. We will get rid of all cook methods
and their ambiguous names, just rewrite some like client... provider...
