A coroutine without a yield statement can be defined simply and
concisely, thus:

@coroutine
def f():
      return 1

A pure-python definition of the "coroutine" decorator is
given below.


[]

from types import FunctionType, CodeType

CO_COROUTINE = 0x0080
CO_GENERATOR = 0x0020

def coroutine(f):
      'Converts a function to a generator function'
      old_code = f.__code__
      new_code = CodeType(
          old_code.co_argcount,
          old_code.co_kwonlyargcount,


This is joke right?
Well it was partly for entertainment value, although it works on PyPy.

The point is that something that can be done with a decorator, whether in pure Python or as builtin, does not require new syntax.

Cheers,
Mark.
