Peter -
1. The BNF (at least the AMS LRM) just says
range ::=
[ constant_expression : constant_expression ]
There is no constraint that the expressions be integers.
2. and 3. If the simulator tried to implement them as an
array, then this would happen; but a clever simulator
should recognize the multiplicity and take the shortcut
to instantiate the module with multiplicity.
