I already raised this concern during the initial discussions, and Mark came up
with nice solution.

Instead of having an additional stateful global interface that code would have
to check in addition to the "skipna" argument, you can have a simple function
that takes and/or constructs an ndarray and redefines its ufunc wrapper to
always set the "skipna = True" argument.
