Your tastes must be different from mine, then, because
it doesn't strike me as any prettier visually, either.

I don't think I can fully separate these different kinds of
aesthetics in my mind, anyway. To me, a piece of syntax
isn't just something to look at -- it has a grammar, and
it has a meaning, and if the grammar and the meaning and
the way it looks on the page don't all agree with each
other, it strikes a discordant note.

When I read the syntax

  def foo(args) [classmethod]:

it says to me "Define a function foo, with these args, and
which happens to be a classmethod. Here's the body..."

On the other hand, when I see

  def foo(args):

the little voice in my head doesn't really say anything
coherent at all.
