Could #find_renderer be changed to not just instantiate?

[kennethkalmer]

Would you accept a patch to update the BaseNodeRenderer#find_renderer method to not just blindly instantiate a class, but instead If the renderer responds to #call, call that with the mappings & node. This allows for whoever is doing the renderer to pass their own lambdas or instantiated objects in with more state.

My particular use case is for rendering referenced entries. Having more configurable renderers that I can instantiate on my own means I can pass along a reference of all the referenced entries and continue rendering recursively.

I appreciate this will change the method signature to pass the mappings along with the node to #render, and there should be a backwards compatible way to do this
