Subject Re: peristant and immutable collections

To clarify my point:

We would copy the code over from pcollections. 
The difference is that we do not _maintain_ it in a different project that we have a dependency
We maintain it as part of the core.
Also: pcollections may have other users than Groovy. But Groovy core doesn't have to deal
with that.

Frankly, if I would write something from scratch for Groovy, it would probably end up to something
similar to pcollections again. That is because you normally need some level of interoperability
(or easy wrappers) for the collection stuff, since so much in Groovy does use it already and
since so much of it has special treatment in the runtime.
