Both answers are far from ideal because you cannot assign to a List
anyway, even when you use an existing position.

Today (2017.11,HEAD(e5b660e)) it prints this message​:

Cannot modify an immutable Str (Nil)

Fixed with c9699ab , tests needed. Please note that this currently breaks tests 55-56 in S02-types/range.t which appear to be a little too specific for their own good.
