See my previous reply.  It's not about (what you called)
constants and mutability.  Misleading, and unclear, IMO.

> I didn't think of recommending ways of coping with it

I don't think that's needed.  That is, I don't think
there's any such "coping".

What's needed is to make clear to users _what_ happens,
and its effects; that's all.  With that info, they can
do whatever's appropriate for them in any given context.

But it's good to show an example of a gotcha, to help
make clear _what_ can happen and why.
