Hmm, IIRC both (Extended) Pascal and PL/I allow VLA within function
in places where they allow variable declarations, so really no
special _inner block_ requirement (just must be local to a function).

I had other languages in mind.[*]

[*] For example Simula:

begin
    integer n;
    n := inint;
    begin
        integer array arr (1:n);
        arr(5) := 9;
    end
end

(Which is also understandable, since in Simula declarations must appear
before statements in any block.)
