[Vala] Genie syntax for connect

["Phil Daintree" <phil logicworks co nz>]

There are a number of examples at code.valide.org that show the old syntax for connect ing signals to 
functions for the most part the function name is simply a parameter to the connect() method of the signal. 
However, where the function is coded in line there was an alternative syntax like:

Slider.value_changed += def (s)
    spin_box.set_value(s.get_value())

It still works but is depreciated. What's the new syntax for doing this?

Thanks
