Which popular programming languages provide proper ACLs (or equivalent functionality) for class members?

I'm aware of C++ and Xojo for sure.

Is it possible to have a proper compile time ACL for C++?

Arguably the Badge pattern as presented in the article is just an honor system that provides zero security, since it's trivial to forge a fake Badge: https://repl.it/repls/BountifulQuerulousCron

It's less trivial if you make the copy/move constructors private.

Of course, type systems are orthogonal to any real security, at least in most languages, and certainly all languages with no-holds-barred interface to machine code.
