BTW, a similar issue (pitfall) I faced was that I sometimes expect that
when a variable is already bound, already the first appearance of the
symbol would be turned into an equality test.
I wonder if pcase variable bindings could be hygienic in the sense that
they would use fresh symbols internally. That would maybe make the
semantics clearer.
