[Ironpython-users] WDB web debugger for IronPython

In other news, I've been trying to isolate the issue and finally found out
that dis.py findlinestarts(code) is throwing a NotImplemented when trying
to access code.co_lnotab, which is not implemented in IronPython -
http://www.nudoq.org/#!/Packages/IronPython/IronPython/FunctionCode/P/co_lnotab
So that's probably it, and now it's only a question why instead of
reporting this error it spins off into trying to compile and optimize this
function.
And I'm off trying to find out if I can make the debugger work.
Thanks for reading :)
