Implement warnings for data that can't be serialized

[pirelenito]

• nested props containing functions
• functions in handler callback arguments

[xaviervia]

So, there are two places where the user can try to send non-serializable data:

1. In Scatter:
   • Any prop that is not a function or a JSON serializable value
   • In particular functions deep in the object tree could trigger a different warning (since they can be assumed to be handlers placed there by mistake)
2. In Materialize:
   • When sending data back through a handler

Correct?

Exactly!
