 ### Example for `compute_reactive_node`
 
+Let's compute the `ReactiveNode` for these two expressions:

 julia> e2 = :(weather() = magic() + science);

 ```julia
 julia> r1 = ExpressionExplorer.compute_reactive_node(e1)
 ExpressionExplorer.ReactiveNode(Set([:+, :magic, :science]), Set([:weather]), Set{Symbol}(), Set{ExpressionExplorer.FunctionNameSignaturePair}(), Set{Symbol}(), Set{Symbol}())

+Second one, note that `weather` is a function definition, so it does not show up in `r2.definitions`. If you want everything that is defined, you can use `r2.definitions ∪ r2.funcdefs_without_signatures`.
