S3 should raise Contraint_Error - or potentially issue a compiler warning / error on obvious cases.

Note that this proposal should also be generalized to multi-dimentional arrays, where one or more of the lower bounds could be fixed,

for example:

type Int_Matrix_1 is array (Positive range 0 .. <>, Positive range <>) of Integer;

type Int_Matrix_2 is array (Natural range <>, Natural range 0 .. <>) of Integer;
type Int_Matrix_3 is array (Natural range 0 .. <>, Natural range 0 .. <>) of Integer;

The behavior should be similar to the one of single-dimension array, including in particular subtyping, assignment and slicing/sliding.
