Is it possible to use Java lambdas?

No, lambdas have not be implemented for BaseLanguage. The baselanguage.collections language provides closures to BaseLanguage. Although intuitive to use, the syntax differs from Java lambdas.

Vaclav, can I for example to write something like this with closure?

Thread t = new Thread(() -> {
        foo();
    });

Yes, you can. I look like this, though:

Thread t = new Thread({ => foo(); });
