Still arguably clunky, still doesn't have any performance benefits,
but possibly a better interface to function attributes than just using
them in their raw form.
def static(**statics):
def deco(func):
for name, value in statics.items():
setattr(func, name, value)
func.__globals__["__me__"] = func
return func
return deco
@static(a=1)
def f():
print(__me__.a)
