Yes. cl-lib has a couple of neat tricks up its sleeve, still.
And what about keyword arguments in plists? Can pcase
destructure them? If so, does it bind the "supplied-p" variable?
And can it rename the variable being destructured to something
else non-clashing?
All these things are useful in CL's destructuring-bind,
but it is missing other stuff like "casing" logic. So
at least on a first glimpse, this reunion would be
welcome by me.
With the caveat that I haven't seen any examples or the
patch yet, and it matters.
