This match statement (or would it be an expression?) could be regarded
as an extremly simplified syntactic variant of the case-of expression of
Standard ML[1].
Instead of the pipe operator we could use a comma to separate multiple
“patterns”. Using “case” instead of “match” appears to be something to
consider as well.
