It looks like a language implementation hole (if this is true, 
then it should be regarded as a bug to be fixed).

Ok, with ints 2.065:

http://dpaste.dzfl.pl/5057b6ce3ff8

And git head says
Error: Array operation a[] * 10 not implemented

Too strange.
But that compiles:

Ok, if i rewrite my example in such way:
http://dpaste.dzfl.pl/f7aa6aa96821

Should i report a bug?
Thanks!

This compiles:

void main() {
     int[] a, b;
     b[] = a[] * 10;
}


Also this:

void main() {
     int[5] a;
     int[5] b = a[] * 10;
}


In general D array ops are designed to not allocate memory. But I 
think their design has some holes.
