By the way, as previously noted
d[1, 2]
d[(1, 2)]
are at present equivalent. However, in the new syntax
d[1, 2, a=3]
d[(1, 2), a=3]
are not equivalent. (The first has three arguments, the second two, the first of which is a tuple.)
In the "New syntax", wouldn't these examples map to:
d[1, 2, a=3] => d.__getitem__((1, 2), a=3)
and
d[(1, 2), a=3] => d.__getitem__((1, 2), a=3)
I.e. My understanding was that the existing conversion of all positional parameters in a subscript would be packed into a tuple (strictly for consistency with legacy behaviour) while any keywords would be passed as kwargs?
