Bug 13999 – [REG2.067a] Associative array literal with static array keys must now have matching key lengths

--- void main() { string[immutable(dchar[2])] aa = ["ああ": "foo", "あ": "bar"]; } --- test.d(3): Error: cannot implicitly convert expression (["\xe3\x81\x82\xe3\x81\x82":"foo", "\xe3\x81\x82":"bar"]) of type string[string] to string[immutable(dch ar[2])] --- Using DMD 2.067/master at the time of posting. This used to compile, for better or worse. Changing the second entry's key to two code points, like "ああ", makes it compile. Not sure if this is now a DMD or druntime issue, or both. Although tangential, the error can be really hard to find in big literals.
