>>> IronPython.Compiler.Options.TraceBackSupport
True

Looking a bit further - the third result of sys.exc_info() (the
traceback) is always None. Is this the case on .Net as well? I'm not
sure that this is relevant, because the inbuilt traceback code is
dumping out a working traceback (well, aside from the line numbers), I
suspect this is a different problem.

I'm not sure what the options are for debugging C# code under Mono are
- MonoDevelop has an 'import Visual Studio.NET project' option, but
that appears to choke on the project and solution files in IronPython.
Wah.
