It would not be more complicated in substance.  It would only be less
terse in the way it is written.

I hope it will be similar but avoid the tersd syntax.
I have not finished design it, but I made some progress today.

Would you like to help design matching functions to do the same jobs
that pcase does?  I would like to make it possible to combine
various matching and destructuring functions using `and' and `or'
(plus any other Lisp functions you like).
