BTW1, there is also a

 (not PATTERN)

pattern form that already works but is not yet optimized, thus fully
undocumented.


BTW2, I discussed with Stefan the semantics of a `pcase-setq', and how
it could be connected with generalized variables.


BTW3, we were not yet all agreed how the semantics of `pcase-dolist'
should be when the pattern doesn't match (currently, AFAIK, it loops
nonetheless).  Similarly for pcase-let and pcase-lambda.  For some of
these forms, we do not yet know how useful they are.

Just some examples of open questions that shows that some stuff is still
a bit of work in progress.


Michael.
