You mean that declaring "twice" is smarter than declaring just once?
You need two declarations: one for the type of the typed pointer, and
one for the typed pointer itself. The Pascal type is visible in the
pointer type declaration, and not in the pointer declaration (which is
in a different section, var vs. type, which in a large program can be
quite far away).
I hardly see the point.

You mean that string or object references where pointers are implicitly
dereferenced make the code less readable?
A MyString^ or a MyButton^.Click would be more readable than the
current MyString and MyButton.Click?
It would be more consistent with the rest of the language, but what I
suggest is to push consistency on the opposite direction.
