Use a shaped hash with a key type that defines infix:<===> appropriately, since object hashes are based on infix:<===> rather than infix:<eq>. : Or broader: that the keys should be normalized (think NFKC()) before : usage? I think it would be up to the type to generate, transform to and/or cache such a canonicalized key. : Would it be easy to "delegate it to the hash"? (or use a hardly : noticeable wrapper) Probably--just give the hash a shape with a key type that is easily coerced from the input types, I suspect. Hash keys could probably afford to do an implicit .as(KeyType) even if the current language were to disallow implicit conversions in general. Larry
