        sub &infix:<==> ( Any $x, Any $y ) {
                +$x === +$y; # propagate coercion failure warnings to caller

        sub &infix:<eq> ( Any $x, Any $y ) {
                ~$x === ~$y

So the purpose of === is to provide a means of comparison that doesn't
implicitly coerce its arguments to a particular type?
