[rules-users] Alternative to instanceof when matching against multiple concrete types under the same hiearchy?

[laune]

Inverting the order of patterns (and following Lisa's idea) makes the problem
go away:

rule "asdf"
when
    OtherType( $member : member )
    Interface( this == $member )
then
    // do whatever with $member
end

This can be constrained to a subset of subclasses if there is also
ConcreteType3 extends Interface which should not be matched by adding
expressions using instanceof.
