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.

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

[hardburn]

Pseudo-hashes are deprecated anyway.

Right, but the use fields; interface isn't and you can use it to create struct-like objects.
