True. I don't feel strongly about this. My guess is that at least at
the level of the Axes.fill method, a user would almost never want the
open-yet-filled case, but I could be guessing wrong, or the "almost"
qualifier could be critical. We could do automatic closing only at that
level, however.
Maybe the best alternative is to leave the trunk behavior as it is, and
make sure the documentation is very explicit about the need to supply a
closed path. This change could be added to API_CHANGES, as well as to
the Axes.fill docstring.
Does anyone know how Matlab, IDL, etc. handle this?
