Hi Armin,
Thanks for the help! I tried your suggestion, and I get the following error
when I try to call that function on a wrapped object (instead of
_my_extra_dict, I named the attribute "rbflags" and called the function
get_rbflags) :
Attribute 'rb_flags' on <ClassDef 'pypy.interpreter.baseobjspace.W_Root'>
should be read-only.
This error can be caused by another 'getattr' that promoted
the attribute here; the list of read locations is:
(pypy.interpreter.baseobjspace:39)W_Root.get_rbflags
v1066 = setattr(self_275, ('rb_flags'), v1065)
In <FunctionGraph of (pypy.interpreter.baseobjspace:39)W_Root.get_rbflags
at 0x65b54e90>:
Happened at file
/home/ubuntu/pypy2-v5.3.1-src/pypy/interpreter/baseobjspace.py line 41
==> self.rb_flags = {}
Known variable annotations:
self_275 = SomeInstance(can_be_None=False,
classdef=pypy.interpreter.baseobjspace.W_Root)
v1065 = SomeOrderedDict(dictdef=<{SomeImpossibleValue():
SomeImpossibleValue()}>)
Processing block:
block@15 is a <class 'rpython.flowspace.flowcontext.SpamBlock'>
in (pypy.interpreter.baseobjspace:39)W_Root.get_rbflags
containing the following operations:
v1065 = newdict()
v1066 = setattr(self_275, ('rb_flags'), v1065)
--end--
