Please, why the following code:

int main (char[][] args)
{
int[] a;
int[] b;

a.length=5;

a[]=3;

b[] = 2*a[] ;

return 0;
}

produces the compiler error (on line 10):
"
: incompatible types for ((2) * (a[])): 'int' and 'int[]'
: 'a[]' is not an arithmetic type
"
?
Thank you very much for help,

Whole-vector math has not been implemented yet, and i recall the manual states it somewhere, though probably at a surprisingly unrelated spot.
