Why hide the tracebacks? sys.tracebacklimit = 0

[eduardoalmeida]

I really like this library but it is impractical for me to use it with unit tests if the traceback is hidden. If there is a lot of expects and it fails in one of them, there is no easy way to know which one failed. What I´m doing is setting it back to None after I import expect. Is there a reason to set it to 0?
