Hmm, that's a surprise, coming from you :-)

Method annotations can be made to do function attributes:
for k in kw:
setattr(func, k, kw[k])
def func() [attrs(a=1, b=42)]:
but I don't recall how they do properties (and let's not have the
"extended function syntax" thread again, please).
Now this is what I don't get. Nobody said absolutely anything
bad about anything. Yet it is always possible to just pull
random flames out of ones ass.
