Hi,
i would like to create a function which takes the first parameter as a reference to a struct - but assure the calle that the reference is read-only. Can this be done?

If i am not mistaken, then the "in" Parameter Storage Class is what i want(?). But the documentation states that this feature should not be used.

For context: I want to write struct-methods outside the struct (like in golang).

Yes, you can do this with `ref const`.
