Removing items positionally from a vector about mori HOT 6 CLOSED

I'll think on it, thanks for the feedback.

I think splice doesn't really make sense since it really cannot be done efficiently for vectors. However good progress has been made to Clojure RRB-Vectors which do support this. I'll likely be including this in the future.

I'll look into indexOf

Thank you, Sir. The lack of this is certainly not a deal breaker.

I am wondering about something related to vectors and if all the crud operations are implemented in a manner that allows for efficient structure reuse. I can see how to create and read the vector; that's straightforward. I can update items at a particular position with assoc, but how would would one remove an item at an arbitrary position?

var v = mori.vector(1, 2, 3, 4, 5);
var v2 = //do what here?
mori.into_array(v2) //=> [1,2,4,5]

The only thing I found is:

mori.into_array(mori.concat(mori.subvec(v, 0, 2), mori.subvec(v, 3, 5)))

But I would have expected:

mori.into_array(mori.concat(mori.subvec(v, 0, 1), mori.subvec(v, 3, 4)))

Or better yet:

mori.dissoc(v, 2) //but this doesn't work for vectors

All I am really after is the most efficient means of removing a portion of a vector while still reusing as much of the original structure as possible. It would seem a waste to have to reconstruct an entire vector, esp. a large one, just to remove a single item. Without this feature the crud operations are incomplete.

This sort of thing can be done properly with RRB-Trees.

OK. So then not in Mori's scope.
