I like the idea of configuring the list of variables with using a
convention like __trace__, though this requires me to specify what
variables cause an exception and that would be hard?
The idea is that you simply use __trace__ to format the local
variables for that frame. In other words, the programmer specifies
what they want to see at that point in the traceback, by setting a
variable in their code. If there's a __trace__ variable in the frame
locals at that point in the traceback, simply format the traceback
locals+globals using that string's .safe_format() method.
May be we could add a loglevel or something; or we keep it simple as it
is now but respect __trace__ if it is there.
Right - I'm saying, if there's a __trace__, you would just use that,
and otherwise either include local variables or not, depending on
whether they were requested in the traceback formatting call.
