I'd like to hear more about why the empty tuple has been selected as
the default index.
It makes sense to me: if more than one index is passed, they are passed
as a tuple. so many classes need to handle tuples anyway.
What other options are there? I suppose None is a possibility, but None
is a valid dict key, so probably not a great idea. Hmm, so is an empty
tuple. Darn.
I think having no default is a better option, as someone pointed out
already in this thread.
It currently doesn't support multiple indexes, so there's no distinction
between one index that's a 2-tuple and 2 indexes: d[(1, 2)] == d[1, 2].
Using an empty tuple as the default index isn't that bad, assuming
you're going to allow a default.
