by Tim Mackinnon

That makes sense - but in a practical usability sense its broken - it doesnât give me a useful breakpoint to step through code where I expect. Should I raise a Fogbugz for this? Or should we just remove this feature if we canât do it right?

You can see the "real" bytecode of the contexts method if you select GTs bytecode view.

I think this is more of a FastTable / GT issue than DataFrame, so maybe the discussion should stay here? (if anyone is interested :-)). Thanks, Alistair
