As I said in the linked thread, I am extremely against using get/set terminology because it is actively misleading.

This is your explanation in the other thread:

@RustyYato

Using get / set terminology is actively misleading because it gives the impression that you can't mutate fields that you only have get access to.

I think this is not true. Having a getter doesn't mean that the returned value is immutable. It's not true in Rust, and it's definitely not true in other languages.

I am thinking about renaming the feature to non-settable fields.
