--- Comment #15 from Denis Shelomovskij <[email protected]> --- (In reply to Walter Bright from comment #13) > ... > Yes, the compiler currently accepts const keys, and const keys are mutable > by other references. But that is the bug, not the error message about > immutability. > ... If accepting not implicitly convertible to `immutable` types as associative array keys is a bug, please approve Issue 12491. --
