Shouldn't you be using walkLength instead of sum, since you are
counting the left over values?
import std.range : walkLength;
writefln("Count is: %s", arr
.filter!(a => a==false)
.walkLength);
That would work also yes.
Be interesting to know which is more efficient actually - I
suspect they're very similar.
