The answer depends on whether you have accessed the B instance through
bla (or wrote an instance into it).
Aor example, right after "a = A.get(key)", pickling a will not pickle
the B referenced by a.bla.
Moreover, after you do "a.bla = {B instance}.key()", pickling a will
not pickle the B referenced by bla.
However, after you do "a.bla = {B instance}", pickling a will pickle
the B referenced by bla.
And, after you do "None == a.bla" or reference "a.bla.b_field",
pickling a will pickle the B referenced by bla.
