Hmm, set() sounds very generic, setItem() might be better.
For the list situation, what does it add over the use of an index:
call set(list, idx, val)
let list[idx] = val
Don't these two commands do exactly the same?
Similarly, for at dict:
call set(dict, key, val)
let dict[key] = val
The problem is that using a function doesn't work:
let GetList()[idx] = val
let GetDict()[key] = val
Instead of implementing set(), wouldn't it be better to implement this?
