This is a str versus repr problem. I've attached a patch to #5220 which
fixes it, but this patch also changes how interact deals with strings.
The patch should be discussed before applying, I think, since it changes
the way strings work as arguments to interact things.
@interact
def plotfunction(f=input_box('x^2')):
print f
before used to give a box with x^2 in it. With the patch at #5220, it
gives a box with 'x^2' in it (note it is now explicitly a string).
To prevent applying without discussion, I intentionally left the two
existing doctests of the affected function broken. I figured that would
stop mabshoff from applying the patch until discussion happened and
someone cared enough to fix the existing doctests :).
I think the correct behavior should be the behavior with the patch.
Thanks,
Jason
