Description

This is the suggestion as distilled from the mailing list:

a) Add the return value to the eval() method

b) Wwe create a new SlingScript.call(String method,
Object... args) method which will be implemented such, that a new
(virtual) script is created from the original script appended with the
method call.

Example: Let the script source be

function sampleFunction()

{ ... }
function anotherFunction(arg1, arg2) { ... }

Now, we call script.call("sampleFunction", null).

This would result in the virtual (combined) script:

function sampleFunction()

{ ... }
function anotherFunction(arg1, arg2) { ... }

sampleFunction();

Likewise, calling script.call("anotherFunction", 5, "astring") would get
the virtual script:

function sampleFunction()

{ ... }
function anotherFunction(arg1, arg2) { ... }

anotherFunction(5, "astring");

To build the method call, we may use the
ScriptEngineFactory.getMethodCallSyntax().

Finally the virtual script is actually evaluated.

This would also allow this for any scripting language ...
