Ah yes - you're correct....

I was over-simplifying... (neglecting templates and function-overloading
situations...)  I should have said that I was speaking in more simple terms.
Basic C-like expressions...

And, I think, my assertion breaks down in the delete[] situation as well.

(Although, in your example, you didn't access the 'arr' array, only the
number of elements.... so, a twisted argument in the template situation
could be had... but, in truth, my "blanket" statement is clearly too 
simple.)

I tend to lean more toward "C-isms" where the type is less involved in
distinguishing behavior.

I was also trying to motivate the idea of "pointer to first element".
Hopefully, my attempt to make that point isn't lost in the morass of
other issues.
