A modern list library for Emacs
I just noticed a fairly significant difference between how `if-let*` and `-if-let*` handle binding in the ELSE clause: ```el (if-let* ((a 'a) (b nil) (c 'c) (d 'd)) t (list...
An `-interleave` that interleaves *all* elements of all lists.
I find the `-comment` macro to be as usefule in Elisp, as the [comment](https://clojuredocs.org/clojure.core/comment) macro is in Clojure. I think it deserves to be part of the dash.el.
I'm using the latest compiled Emacs, and if a macro named `x` is defined elsewhere, loading `dash.el` will fail. Reading the source code, find that it is because the `cl`...

Emacs 26 will have a new feature: > New built-in function 'mapcan'. It avoids unnecessary consing (and garbage collection). For functions like `-map`, etc, I guess it would be good...
The following useless code probably shouldn't throw an error: (-setq (_) '(1)) Fails with "Attempt to set a constant symbol: nil". That goes for anything where the destructuring form is...
Can we have some functional concurrency primitives, like a concurrent map that runs some function on a sequence concurrently? Of course, parallelism would be best, but I think emacs threads...

Forgive the many submissions. If you want me to stop, just say so. :) When I was working on org-super-agenda recently, I needed to group items by whether a set...
