grep for pcase-defmacro: that should give you a good starting point.

I don't think the `seq' pcase pattern can be defined using seq-let, but
seq-let could easily be defined as a wrapper that expands to a pcase-let.
BTW, another advantage of defining a pcase pattern is that you could then
also do things like
(pcase-dolist ((seq a b c) my-things)
...)
