-----------------------------------------
As this patch has some drawbacks, is it worth applying it nevertheless?
> Scala Scripting: Make all types of the script arguments visible on the Scala
> side

> Key: SLING-1236
> URL: https://issues.apache.org/jira/browse/SLING-1236
> Project: Sling

>
> Currently the Scala scripting engine inserts a preamble for the bindings
> passed to a Script. The preamble contains a declaration of the following form
> for each value in the Bindings instance:
> val request: SlingHttpServletRequest =
> bindings.get("request").asInstanceOf[SlingHttpServletRequest]
> The types are hard coded in the ScalaScriptEngine.TypeHints class. For
> unknown types a declaration of type AnyRef is inserted into the preamble.
> I suggest to implement a run time type discovery algorithm which discovers
> the accessible type from a given instance and inserts the respective
> declarations into the preamble. That way the static coupling between the
> known values in Bindings and its types would go away. Furthermore the values
> would be of a type appearing to be of all the visible types on the Scala side.
