I was thinking this morning that such a move will run a high risk of(i don't have a deep understanding of the issues so this might be completely left field.)
creating a circular dependancy between [collections] and [lang][functor]. It
seems likely that functors would want to use collection objects and
vice-versa. If I'm right about this, then all this code really belongs under
the same package.
i suppose that it's the implementations rather than the interfaces that will depend on collection objects.
this might point towards having a separate (possibly revamped) pattern component. the interfaces might live in lang and the implementations in pattern. pattern could depend on collection whereas collection could depend on lang.

I'm having a lot of trouble seeing lang as meeting the "Each package must have a clearly defined purpose, scope, and API -- Do one thing well, and keep your contracts." criterion. Don't get me wrong, I think all of this is great stuff, but why does it all have to be in lang? If it doesn't meet the common reuse principle, it should be in a different component. The current (i.e., released) contents of o.a.c.lang, o.a.c.lang.builder, o.a.c.lang.enum and o.a.c.lang.exception seem reasonably coherent, but I don't think the either the functor or the reflection packages are a clean fit (with respect to the CRP, R/REP, etc.), either with each other or the other classes in lang.
