Reddit improvement proposal - CSV slices

[fred1268]

Do you have any thoughts on allowing CSV slices?

e.g --my-args one,two,three,four,"five has a space",six

Alternatively, flag repetition to allow slice args?

e.g --my-args one --my-args two ... --my-args "five has a space"

The reason I ask is knowing the argument count for non-trailing as is specified in the example [4]string seems odd.
