Description
At the moment a single pattern forall statement like
forall( Type( constraints ) )
it is automatically rewritten as
forall( $t : Type() Type( this == $t, constraints ) )
and then implemented with 2 not nodes and join.
[EntryPointNode(1) EntryPoint::DEFAULT ] on Partition(MAIN)
[ObjectTypeNode(4)::EntryPoint::DEFAULT objectType=[ClassObjectType class=org.drools.testcoverage.common.model.Person] expiration=-1ms ] on Partition(MAIN)

[NotNode(7) - [ClassObjectType class=org.drools.testcoverage.common.model.Person]] on Partition(1) Ld -1 Li -1 Rd 9223372036854775807 Ri 9223372036854775807

[ObjectTypeNode(2)::EntryPoint::DEFAULT objectType=[ClassObjectType class=org.drools.core.reteoo.InitialFactImpl] expiration=-1ms ] on Partition(MAIN)
[LeftInputAdapterNode(3)] on Partition(1) Ld 0 Li 0

[NotNode(9) - <source from a subnetwork>] on Partition(1) Ld 0 Li 0 Rd -1 Ri -1
It would be much faster to rewrite it as
not( Type( !constraints ) )
and then evaluate it with one single not node.
