# Very special nil hack: in order to allow W_PointersObject's to
# initialize their fields to nil, we have to create it in the model
# package, and then patch up its fields here:
- w_nil = self.w_nil = model.w_nil
- w_nil.space = self
- w_nil.s_class =
self.classtable['w_UndefinedObject'].as_class_get_penumbra(self)
+ def patch_nil(w_nil):
+ from spyvm.fieldtypes import nilTyper
+ w_nil.space = self
+ w_nil.fieldtypes = nilTyper
+ w_nil.s_class =
self.classtable['w_UndefinedObject'].as_class_get_penumbra(self)
+ return w_nil
+ w_nil = self.w_nil = patch_nil(model.w_nil)
w_true = self.classtable['w_True'].as_class_get_shadow(self).new()
self.w_true = w_true
