OK, I see your point. I'm working on a patch that does the following:
def view(type_or_dtype=None, dtype=None, type=None):
raise ValueError("Cannot specify dtype twice")
raise ValueError("Cannot specify type twice")
type = type_or_dtype
dtype = type_or_dtype
Would that be a satisfying solution? I'll be back around 21:00 SAST
to attend to the matter.
