[pypy-dev] Traceback surgery

[Maciek Fijalkowski]

I've got an issue about distribution lib. I would like to do a bit more 
surgery of presented traceback, which needs cutting and sticking it back 
together. On top of cpython it's impossible, because this stuff is read 
only (you cannot modify tb.tb_next for example). Do we have a good 
reason why readonlyness remain in pypy? Of course I can cheat and use 
transparent proxy for that, but as long as this code would never work on 
top of cpython, can we lift those restrictions?

Cheers,
fijal
