    I need to have another look at groovy, and how far its eclipse support
    has come since the last time I tried it.

    The lack of support in the wizards is more an inconvenience, than an
    obstacle that would prevent you using scala or groovy. I wouldn't be
    in a rush to support such things in wolips unless you are actually
    using them yourself ongoing, else they will likely wither on the vine.

    The real issue is whether WOLips' component integration and binding
    validation would still work effectively or not. I suspect with scala
    it probably will to a point, but with groovy it would depend on what
    ended up in the bytecode. Generic type parameter resolution will only
    work with java because WOLips introspects the source code using JDT.
