---------------------------------------------------------------
I restored the true return for WriterController#isInClosure for lambdas. The
test case mentioned in the description works correctly now. The additional
test case for static property += is throwing NPE. I will try to see why this
is. Your proposed change to VariableExpressionTransformer or some kind of
change in classgen may still be required.
