[IronPython] Getting a line number of error (RC2)

[Matt Beckius]

Well, I guess since CPython does provide it, I would expect IronPython to.
More importantly, I am embedding IronPython in a hosting app, and I'm trying
to accurately report where errors occur.  When an error occurs due to
something like I previously outlined, only a ArgumentException is raised (I
don't get a line number),  I tried adapting Dino's example by calling
pythonEnging.Sys.exc_inf(), but the tuple's 3 memebers are null.

TIA,

MattB
