bug to take a look at that too. Even if we expose the frame information via
sys._getframe() there will still be some missing information that’s hard for us
to produce, but it might be able to unblock a number of useful scenarios.<o:p></o:p></span></p>

color:#1F497D'>In a related problem, could you guys take another look at
sys._getframe when implementing this feature? There is a lot going on in
the returned frame object from that function, but I think the big holdup for
this is the stack frame information. If the answer is still “no we aren’t
ready for that,” this is ok, but I figure after implementing stack frame
support within the DLR would be a good time to look at this.<o:p></o:p></span></p>

color:#1F497D'>Unfortunately there’s no good way to do this. We have
logic in PythonEngine to filter stack frames but it’s only exposed for doing
this on exceptions, not on arbitrary stack traces. And unfortunately v2.0
is in about the same shape – all of its support revolves around exceptions too
and it’s filtering is probably even less useful than v1.x’s for these
purposes. <o:p></o:p></span></p>

seem like something that will be fundamentally needed (especially as more
languages run on the DLR) and it’s pretty basic functionality. The bug
