RM83 4.1.1(4)
... The exception CONSTRAINT_ERROR is raised if an index value does not belong 
to the range of the corresponding index of the prefixing array ...


A: array (Some_Range) of Something;

I: Some_Range;
J: Integer;

A (I) - the range check can be omitted
A (J) - the range check cannot be omitted if Some_Range is smaller than Integer
