FYI...

If you don't need b, you could also do this:

        def button().onClick():
                print "You clicked me"

If you need b and you want to write compact (some would argue Perl-like)
code, you could use a new syntax we are debating right now that allows
assignments-as-expressions with ":=".

        def (b := button()).onClick(): print "You clicked me"

There are valid non-Perl-like uses for := also. :-)
