I was referring more to the fact that you don't need parentheses around
that—if I remove the leading space, it looks like @ is an operator that
operates on the first `Spam()`:

    @Spam() + Spam()
    def func()
        pass

while instead it's just part of the (compound) statement syntax for
function definition.

If one had to think of @ as an operator, it would be a unary operator of
the absolute lowest priority. So, from a code style perspective, should we
add a space between it and the expression? This should be discussed and
added to PEP8, it's a very transcendental matter! ;)
