Yes. Do note though that this will allocate a new array, and not *copy* filter
"into" the "d" array. Not that it's wrong, I just want to highlight it, as I
don't think its quite what the op wanted.
If you want to assign the *contents*, then std.algorithm.copy will do what you
want:
http://dlang.org/phobos/std_algorithm.html#copy
int[] d = [1,2,3,4,5,6,7];
d.filter!(x => x > 3)().copy(d);
