[Ironpython-users] Options for debugger for DLR languages on Mono

[Dino Viehland]

Is the hosted IronPython running in the same ScriptEngine or a different one?

If it's a different one you'll need to do the settrace on the other ScriptEngine but
you should be able to do that from Python code as well.  

If it's the same then I would expect that you'd see the traces for both the hosting
and hosted code (I'd also consider separating it into 2 different engines so that
you should only see the traces for the hosted code, or you could look at the args
and see if it's the hosting code and ignore it).  But if they're the same and you're
not getting the trace events for the hosted code then that could be a bug.
