I agree in principle and would be happy to work with you on this,
but there are some fundamental differences between syntax-case and
general-purpose matchers like match-case that might prevent their
unification.  If we can't make them 100% the same, perhaps we can still
make them compatible in some sense so that programmers familiar with one
can easily use the other and so that implementations can use a common
underlying implementation.
