I'll start from the end of the proposal. What about just extending the
keyed syntax:
Px = Py[0] # key
Px = Py["a"; 1] # multi key
Px = Py[0..2, 4] # slice
Px = Py["a", "b"] # slice
Px = Py[I0, I1..] # slice
So a slice PMC is basically a Key PMC with two additional flags per key
component: start_range .. end_range. The comma starts a new key
component. Key components are typed and constructed at compile time, so
we would have already what we need with low overhead.
BTW: is there something like:
Px = Py["a".."x"]
or even
Px = Py["aaa".."xxx"]
