Re: [cdi-dev] New builders API

Before going into detail I wanted to put the accent on the Weld 3.0.Alpha16 release post[1] which give a good explanation regarding this API. Its the best starting point to discover this new API IMO. Thanks Martin, Tomas and Matej for this release. @John. The debate Configurator vs Builder is still open. At the moment we focused on configurator since they are easier to limit to a given container lifecycle, but having builders to reuse the configuration could make sense as well. AnnotatedType is a special case since it could make sense to use it at runtime (to ease creation of an InjectionTarget for instance, so perhaps it will require a Builder. If we keep the API in this spirit for the release, it should be better to talk about Configurator API vs Builder API to avoid confusion for missing build() methods ;) @Antonin the enhancement you propose is very interesting but as Martin said we could imagine a solution to load an existing bean after decision on the API (a mute(Bean) method in ABD perhaps). For me the goal is to decide if we are on the right path and avoid decision that will prevent future enhancement. I think having this API perfect and complete in one PR is almost impossible. So we should validate something to move on missing features or enhancements.
