The advantage J4 has over J2 is that "def function <decorators> as
<body>" reads much better than "decorate <decorators> def function
<body>" - expected from English syntax is 'decorate def function <body>
with <decorators>'. 

Perhaps J2 but with proposal L to call the decorator declaration
something other than "decorate" - 'using' is the best I've seen so far,
though it's still not perfect. Or another idea - how about inverting the
meaning of 'as', and changing the form of the decorator declarations
slightly? 

as:
  classmethod
  memoised
  accepting (int, int)
  returning (float)
def foo(bar, baz):
  .
  .
  .
