Either that or use find and take.

arr.linearRemove(take(find(arr[], elementValueToRemove), 1));

But if you're trying to remove by index, then arr[2 .. 3] makes more sense. If 
it were a container without random access though, you'd be stuck using find or 
popFrontN to to get to the element that you want to remove, and then you'd use 
take to get the first element only (or however many elements you wanted to 
remove).
