Hi,
You can simulate annotation using decorators. I might be missing
something about annotation but you can do this.
def annotate(returns, **params):
def decorate(func):
params['returns'] = returns
func.__annotations__ = params
return func
return decorate
@annotate("returns", a="a")
def f(a):
return a
print f.__annotations__
