It's awkward but can absolutely be learned and taught. What makes it really idiotic is that the spec literally ties visibility to a single, specific unicode character class. This has the hilarious effect that, for example, Latin, Greek, Cyrillic identifiers are allowed to be public, but Arabic, Korean (Hangul) or Thai are not!
