Paul King commented on GROOVY-8133:
-----------------------------------
I changed to a feature request not a bug. It would certainly be nice to support
the spread operator on streams. I think the expectation would be that a stream
was returned. I think it makes most sense to add that for when we require JDK8.
Once we add such a capability we'd then need to potentially tweak the static
compiler to know about it.
