nodes

Groups nodes without connecting them, as in a then nodes(b, c) for an infix fan-out or nodes(b, c).joinTo(join) for a join. Prefer this over listOf(b, c) for fan-outs and joins because listOf infers the nodes' closest common supertype. For some built-in nodes of different types, such as a Workflow and a JoinNode, that supertype is the framework-internal BaseNode, so the call fails to compile.
