Yes, if I ran the circus, I would allow that.  I really find it annoying
that I have to add 3 useless lines of code (declare/begin/end) and an
extra level of indentation, when all I wanted to do was declare
a very-local object.

I also find it annoying that I can't add a statement at the beginning of
a procedure, without moving everything into a local block.  E.g. I have:

    procedure P (X : Integer) is
        Local : constant String := ...;
    begin
        ...

and I want add:

    if X = 0 then
        raise Blah;
    end if;

and I want that to come first.

I agree.  I suppose it comes from Pascal, where declarations and
executable code are completely separated.  It makes no sense in
Ada, where declarations are just as executable as statements.
