In the case of a List, you can construct it by concatenation, though
it might be a little slower at run-time, depending on how densely you
want to comment:
let array = [
\ "one",
\ "two",
\ ] " three is intentionally omitted
call extend(array, [
\ "four",
\ "five",
\ "six",
\ ])
Similarly I suppose for other arithmetic operations: hold the
temporary results in one or more variables, insert the comment after
temporarily ending the computation, and go on from there.
Best regards,
Tony.
