I don't really care how you consider it, but I do care about how you
misrepresent the facts in public.
In another post you said that your language has pass by reference, and
we also know you have implemented C.  Either you are just very confused
and your language simply has call by value (after all, you think C has
pass by reference), or you know that pass by reference in your language
needs something from the implementation that was not needed when you
implemented C.  I can't decide if you are confused or just lying.

I'll cut the remarks I would otherwise make as it's off topic for a C
group.

But when T is an array, its behaviour is more like that of my H function.

So, my remark about arrays in C being passed by reference is understandable.

I have always understood why you say this.  It "looks a bit like it".

But you have clarified.  You have known all along that C passes
everything by value because you have implemented it.  You know how to
implement pass by reference and your C compiler does not implement it.

If somebody had proposed adding pass-by-reference for arrays, you'd say C
doesn't need it, because whatever benefits it might have you, C already
has!

I see you are running out of statements to argue against so you have
started to make up your own.  I am sure you have thoroughly refuted this
made up person in your head.
Anyone proposing adding pass-by-reference for arrays would be told (by
me at last) to start by allowing arrays to be passed by value first.
Why anyone would propose adding pass by reference for a type that can't
be currently be passed at all is a mystery that only you (as the
inventor of this person) can know.

This is my point. Clearly true pass-by-reference for arrays wouldn't add
anything in C;

It would add the ability to pass an array to a function -- something
that C does not have.  How many times will you have to be told?

it already works alike that!

It does not.  It works like passing a pointer by value, not like passing
an array by reference.  You have clearly shown that you know the
difference.  You are now just tolling.
