Denis argues that mutable key char[] should be allowed for the AA indexing.
But AA key should be const on indexing, and should be immutable on setting.
Therefore specifying mutable key char[] is not possible.

(I'm saying if and only if a NewExpression `new char[1]` is directly used, it
can be convertible to immutable(char[]) by the uniqueness. But it's different
from his intention.)

Therefore this issue should be closed as invalid.
