Hi Don,
I assume that it may be related to the cache based on
Collections.synchronizedMap, the implementation is refined via using
ConcurrentLinkedHashMap on parrot branch. Could you give it a try by
following the steps?
$ git clone -b parrot https://github.com/apache/groovy.git
$ cd groovy
Hi Don,
I found the issue is related to another cache issue, so could you
provide some runnable code to reproduce the issue? I'll set asside some time
to investigate it.

If the new operator ?= (e.g. a ?= 'foo' is equivalent of a = a ?:

The new parser(Parrot) supports "implies" operator(=>) now, e.g.

Hi mg,
Parrot is smart enough to distinguish closure and code block, so
`block` is not necessary. BTW, new keywords may break existing code ;)
As for `eval`, we can use `{ /* do something here */ }()` instead, e.g.
`{ 'abc' }()`
