Thanks for the report,
I was partially aware of the issue. The fact is that the current 
prototype does not support the lambda invocation syntax anymore (that 
is, we removed '.()'). As a result, lambda expression should only appear 
'bare' in a method call/assignment context.

I think that, however, the compiler should at least generate a better 
error message in this case; I managed to handle most cases, but not all yet.

Thanks
Maurizio
