Eric Milles commented on GROOVY-8633:
-------------------------------------
I think this example is similar to {{def ABC =
['a','b','c'].collect(String.&toUpperCase)}}, which has not been supported in
any Groovy release. I think the JIRA ticket for implementing Lambdas mentions
this gap/issue as well.
