With dynamic arrays I totally agree. Slicing is very useful. I just want
a safe rule to work with it. Maybe that's not needed anymore because by
now I spend enough time on this that probably I'll never forget.
With in I also disallow changing the object itself, right? I want to
only forbid the changing of the reference of an argument inside the
function. With in/const I disallow every change. I may want to change
data of an array.

The more we talk about it, the more I come to the conclusion that this
is just something you need to know. I can live with that.
