Hi,
what's the best way forward to update the APIs in the inspect module to include the new position information.
These APIs are inspect.getframeinfo, inspect.getouterframes, inspect.getinnerframes, inspect.stack and inspect.trace.
The problem is that these APIs return a named tuple that now needs to include several new attributes (or one 4 tuple for
the positions). Being named tuples, if we add a new attribute, existing unpackings of the tuple will now fail because there
are more elements or the elements are in different positions. Also, it will be quite weird to add the new attributes at the
end but leave the line number at the beginning.
What's the best way to proceed here? The suggested way is to create a namedtuple subclass that adds the extra attributes
but doesn't allow indexed access to it (there is a precedent to this in how we handled updating os.stat_result). I personally
find this quite confusing but it certainly works. There may be other options.
What do you think?
