Yes, static imports.
One can statically import Lambdas.ajaxLink or Lambdas.* and then use it
like:
add(ajaxLink("someId", this::onSomething));
The static method in AjaxLink is named "onClick" though.
The idea here is:
add(AjaxLink.onEvent("someId", this::onSomething))

I've moved them in one place because all those methods share the same
purpose.
I don't mind to move them back though.

I also want to check out Martijn's Lambdas class that he proposed a while
back but didn't commit it due to some problems in javac vs. Eclipse
compiler.
