Re: [abc-users] New around weaving strategy

Hi Eduardo,

We are still working on several different around strategies. The
inlining you see in 1.1.0 is actually an inlining of the original
classID-shadowID weaving and you will note that the way in which it
inlines is different than in ajc. This does sometimes give a
performance improvement in speed, but at a penalty in space.

When we have some time we will be writing a more detailed paper on
the subject of the around weaver, and introducing yet another variation
and studying in depth the performance of the different strategies.

CHeers. Laurie
