I don't count keystrokes. My argument is for readability. I actually
find

with Gtk.Arguments;        use @;
with Gtk.Button;           use @;
with Gtk.Handlers;

more readable than the canonical form. And more pleasing, which can also
be a quality factor. Natural language has lots of pronouns for good
reason. And hey I just found motivation for the symbol choice: @ = a =
anaphoric pronoun :-) In the canonical form you must read 2 identifiers
to verify that they are equal. The pronoun has an immediate reading.
It's more communicative, more lingual. Curiously enough when I first
suggested "use @" I was kind of kidding--it was your very example that
made me realise it is actually more readable.
