Re^5: "Rites of Passage" wheel reinventing

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.	[reply]

Pseudo-hashes are deprecated anyway.	[reply]

Right, but the `use fields;` interface isn't and you can use it to create struct-like objects.	[reply] [d/l]
