Not to belittle that code, but its internal working is very different:
it does not preprocess that `case' into an efficient decision tree, but
instead naively tries each pattern in turn, in many cases performing the
same tests over and over again (even interpreting patterns at run-time
rather than precompiling them). So pcase should show *much*
higher performance (100% untested claim).
