I'm for making our own, Groovy-specific version of persistent data types.
It could become a separate module or live in the core module.
if we are going to use it in groovy-core, it would have to become part of groovy-core. 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.
