[Seaside] calling a JS function

[Boris Popov, DeepCove Labs]

Also, keep in mind that often times you don't need to do #asJavascript yourself, for example you can pass the below dictionary as an argument to a function call and let the framework do its thing for you. The key here is that JSON by definition is an interchange format expressed as a subset of JavaScript, and when you're trying to create a snippet that includes a reference to an object, you no longer have valid JSON, but still have perfectly valid JavaScript.

I get an error: WAError: Override #jsonOn: to make the receiver serializeable as JSON (JSStream on: 'doSomething') returns a JSStream object who doesn't understand asJson.
