Just a suggestion, but the signature could be

opSlice(int[] ...)

where the passed array always had an even number of parameters, and
non-slice parameters get passed as the tuple n, n+1. In that case,
your two cases would be distinguished as [ 1, 2, 2, 3 ] and [ 1, 2, 3,
4 ] (since 1 is equivalent to 1..2, and 3 is equivalent to 3..4).

Only works for ints, but hey! Better than nothing.
