any easy way to increment a value of a key in map? even if the mapping does not exist yet?

I used something like this recently, not sure if there’s a more concise method

map[key] = map.getOrPut(key) { 0 }.inc()

i ended up calling .withDefault() when creating the map and then just
map[key] = map[key] + 1

Does that work? You need .getValue() then, right?
