For readability, reuse and testing I think it often helps to have a
function (whose name is meaningful). We can get this via
as_list_int_literal = gensep(',', '[', ']')
It would also be nice to allow as_list_int_literal to have a docstring
(which could also be used for testing).
I accept that in some cases Chris's ingenious construction has benefits.
