I'm not invested into this in any way, but the variations
+[classmethod]
def f(cls):
pass
or
-[classmethod]
def f(cls):
pass
are syntactically valid today but OTOH differently from plain [...]
correspond to run-time errors.
/[classmethod]
def f(cls):
pass
*[classmethod]
def f(cls):
pass
even better are syntax errors but are really ugly.
I could live with the +[...] form, as I can live
[...]
def f(...):
or
def f(...) [...]:
it's really a matter of "practicality beats purity" and a
compromise/balance issue.
The limits of the parser aren't helping either in this case.
