How to use [return-nodes]

The reference page of return-nodes has its arguments, constraints and declaration.

Returns a bunch of nodes (lambda) from your slot. Can only be invoked from the inside of a dynamically created slot, and other slots explicitly creating a return context. An example can be found below.

slots.create:foo
   return-nodes
      integer-value:int:57
      string-value:Foo bar

signal:foo
