Constraints below fails with exec-model while non-exec-model can execute. Actually non-exec-model doesn't evaluate such an unary expression $n : name so it is equivalent to true. Note that non-exec-model transforms ExprConstraintDescr into ConstraintConnectiveDescr so "&&" is treated like ",".
$p : Person($n : name && age > 20)
