rule A
  when
    Person()
  then
    say “hello”
end

rule B
  when
    Person( name == “Toni” )
  then
    say “get out of here”
end


B overwrites A

We need to generate this:

rule A
  when
    Person( name != “Toni” )
  then
    say “hello”
end

rule B
  when
    Person( name == “Toni” )
  then
    say “get out of here”
end
