Description

Is code like this meant to work? It's useful code:


void main() {
    int[2] data = [10, 20];
    double[2] result;
    result[] = data[] * 0.5;
}



DMD 2.063beta5 gives:

test.d(4): Error: incompatible types for ((data[]) * (0.5)): 'int[]' and 'double'

void f()
{
	ubyte[] a;
	char[] b;
	a[]=b[];
}
Error: cannot implicitly convert expression `b[]` of type `char[]` to `ubyte[]`

Hmm... vector ops are array ops?
