Then what about:
int[string][int] map;
map["abc"][30] = 123;
?
Here, you clearly intend to create a new entry, but currently this
doesn't work. It will throw a RangeError when it tries to look up "abc".
You need the ugly workaround:
int[string][int] map;
map["abc"] = int[int].init;
map["abc"][30] = 123;
