Anyway: are duplicated keys on declaration allowed?
They shouldn't be...
Why? I'll admit it is something I've never even thought of using,
but every language I know (just tested with python, lua, scheme
and js) accepts it and as far as I can tell from a user
perspective boils
auto aa = ["a":10, "b", 42, "a":20];
down to:
int[string] aa;
aa["a"] = 10;
aa["b"] = 42;
aa["a"] = 20;
This is deterministic and could allow one to build an associative
array through a mixin for example while still giving default
values.
As I said, it's not something I've used but I think we should
consider it.
