For example, = I didn=E2=80=99t find any =E2=80=9CTODO/xfail=E2=80=9D in the testsuite. So= me points sound very interesting to me (specifically, 1) adding function po= inter analysis, 2) assumption of reflexivity of constraint-handling, 3) exp= ensive implementation of transitivity in constraint_manager), and I would l= ike to look into these three points if you believe they can be converted in= to a valid GSoC project. Could you give me more details regarding these thr= ee points?=20 In addition, would there be anything related and simple enough that I can w= ork on before the application period?=20 Best, Shengyu= --Apple-Mail=_53EF6765-6CDE-4C0B-B589-7EFB8CFA1CF0--
