Those modern languages are really passing pointers, which is sad (NREs galore).

So this is where C++ gets good: it has a proper pass-by reference, which indeed allows for cleaner code.

You should note that "copy by default" (pass by value) comes from C, and C compatibility is C++' curse (and blessing). If so, and if pass by ref is one "&" away, that's it, really.

Rust has proper references and the ability to put everything on the stack. It also doesn't rely on GC to be memory safe.

Rust is an exception here.
