One big advantage of accessors over passing round a hash is that if you mis-type an accessor name you get an error about an unknown method whereas if you mis-type a hash key you get a bug that may be hard to diagnose.

    That's an advantage in Perl5, yes, but good class design is language-agnostic. There might be a language which provides locked keys for hashes by default, or perhaps you use one of the locked keys implementations in Perl (using a tied interface). Or maybe your language doesn't have hashes, but it has structs which are statically typed and serve the same purpose, and thus a compile-time error is generated anyway.

    : () { :|:& };:

    Note: All code is untested, unless otherwise stated

      Perl5 has pseudo-hashes too, and those offer fixed keys.

        Pseudo-hashes are deprecated anyway.
