Hello, the complex package is turning the addition of two lists which
start with zero into a complex result when it should just be another
list. Case synopsis:
(Plus '(0 1 2 3) '(0 1 2 3)) ;; yields a complex!
(Plus '(1 2 3) '(1 2 3)) ;; yields a list, as expected
(Plus 3 '(1 2 3))
(require-extension array-lib)
(array-strict? (make-array '#() 7)) ; should return #t
However, it returns false... it seems to be a strict array to me.
I do need for a 1-dimensional structure created by make-array to be
testable by some predicate for a procedure I have written called

I've been a fan of J for a long time, and have an implementation of

I think byte-compiling quack.el and putting:

It looks better, because you just seed the state as you please and
then consistently pass the state. This means I can have one RNG that
uses the same seed across interpreter invocation
