Summary0000753: Ranged mapping indexing
DescriptionI'd like to propose ranged mapping indexing, allowing wide mapping values to be accessed as an array. For instance;

mapping map1 = ([ "a": 1; 2; 3, ]);

printf("%Q\n%Q\n", map1["a", 0..2], map1["a", <2..]);

Additionally, it would be a natural extension to use these as l-values, so -

map1["b", 1..2] = ({ 4, 5, });

Coping mapping values from one mapping to another would become a lot easier -

map2["c", ..] = map1["a", ..];

As for the closure versions of these operators, I'd suggest reusing the existing ranged closures (#'[..], #'[<..], #'[..<], #'[<..<]), accepting an additional argument as the mapping key -

funcall(#'[..], map1, "a", 0, 2) == map["a", 0..2]);


I think this would be a logical extension to the language, making wide mappings easier to manipulate. However, I understand how much time these things take and I'd like to express my gratitude for the work being done and to all contributors.

Interesting idea. I'd like to do this, but after 0000546 is finished, otherwise we might code it twice.

The closures should get new names, #'[,..], #'[,<..], etc. (This is consistent with the existing #'[,]).
