Re: [weld-dev] Circular dependencies between dependent bean constructors

Gavin, could you clarify that? From reading your comment, it seems like this use case
implies unbound recursion: Foo injects Bar which in turns injects another instance of Foo
(which is dependent on the first instance of Bar) which injects another instance of Bar
etc.
Secondly, for enabled @Dependent beans without alternatives, is there a real difference
between them and their @New counterparts?

circular dependencies (definition error) or whether it means that they just don't have
circular deps (and that the container must break the circularity.
