> This:
> {noformat}
> global foo: vector of count = { 42 };
> print foo[0];
> print foo[1];
> print foo[2];
> {noformat}
> just prints 42 (index 1), with no warning that 0 and 2 don't exist.  But this:
> {noformat}
>   global foo: vector of count = { 42 };
>   global f0: count;
>   global f1: count;
>   global f2: count;
>   f0 = foo[0]; f1 = foo[1]; f2 = foo[2];
>   print f0; print f1; print f2;
> {noformat}
> yields
> {noformat}
> ... run-time error, value used but not set
> 42
> ... run-time error, value used but not set
> {noformat}
> whereas this:
> {noformat}
>   global foo: vector of count;
>   foo[0] = 42;
> {noformat}
> yields:
> {noformat}
> ... (foo[0]): error, index (0) must be positive
> {noformat}
