Sorry, forgot to mention: I emailed the author months ago, and got no response.

Hi all,

I'd like to take over the `queue` package, last updated 14 years ago, and marked "deprecated" on Hackage. I intend to replace it with a simple, clean implementation of Okasaki's "real time" (meaning O(1) worst-case operations) queue, which you can find implemented here: https://github.com/awkward-squad/queues

I had originally named the package `queues` (with an s), but figured it would be better to repurpose the singular `queue` with something useful, if possible.

Thanks!
Mitchell
