Agreed, I missed this one. It's not too bad with classes if you can warp your mind to think of "to class" as a verb like "to define".

It's more of a replacement for the *[decorators] syntax than the 'decorate:' syntax, but it's an English word rather than a symbol, which brings back a bit more of the "Python look and feel".

One minor nit, why use the brackets at all?

as sychronized, sharkfin(size=10) def VWBug(...):

that looks better to me than:

as [sychronized, sharkfin(size=10)] def VWBug(...):

without brackets it looks more to me like Python, you'd never see:

from foo import [bar, baz]

For longer lists of decorators use the familiar tuple rule, wrap in parens:

as (sychronized, sharkfin(size=10), deprecated) def VWBug(...):
