For Web GUI programming we use Groovy together with Vaadin, and I
recently had some cases, where e.g. an anonymous class method calls a
Groovy closure which calls a Groovy closure which calls a method of the
orginal containing class. In these cases it can become hard to have the
expected method get called, and I also found that (depending on the
situation) either using import aliasing or introducing a uniquely named
helper method in the right class can clear things up quick & easy.
Cheers,

Using import aliases can be a good workaround for such a case.

two things to always remember:
* closure delegation is a runtime mechanism, it has no influence on
static compiled features
* static imports are compiled statically
The later is not because we want this, but because we have to more or
less. And it is painful. I can imagine a system where this is not
required, but that is far from easy or efficient.

In short it is a limitation. I am not sure we can really do something
against that.
