-X:Frames only creates the frame objects and if something happens to
make us promote local variables (e.g. a closure, or a call to locals(),
exec, eval, dir(), vars()) then the local variables will be available
for that specific method.


Thanks Dino. :-)

Try running it with frames switched on:

    ipy.exe -X:Frames

or:

    ipy.exe -X:FullFrames

Perhaps Dino can explain what the difference is between these two
modes... :-)

Any idea what's going on here?
