Check this, updated, example:

Thank you for answering. The example goes like this:
[...]
var button = new Button.with_label ("Click me")
button.clicked.connect (clicked_cb)
add (button)
def clicked_cb (btn : Button)
title = "Hello World"
btn.label = "Hello World"
I don't think that this is a real closure. The idea is, that the
complete callback is defined inside the connect ( def of callback ) like
in the old, deprecated example. Is this possible with connect?

Hello!
An old (deprecated) way to define closures in genie is e.g:
var button = new Button.with_label("Click me!")
button.clicked += def()
button.label = "Thank you"
However, the compiler throws a warning, that this way is deprecated
and recommends 'connect' instead. But, I really can't figure out the
syntax connect works. Has anybody an example for this? Thank you!
