The NSME uses strings for names. It should use symbols. This change modifies the VM libraries only enough to make the signature change not crash. It will probably need cleanup to ensure that symbols are passed to the internal constructor directly, instead of strings that have to be converted. (Also fixes a type error in Map.fromIterable that was hit by the code).
