The function to be run.
The "this" object to be used.
The arguments to be passed to the function. If this is a SCRIPT_FUNCTION the arguments will be set up by this method.
Special meaning variables that are added to the SCRIPT_FUNCTION environment. For example, \_\_new:true means that a modified thisObj will be returned. \_\_yield\_\_:yieldFunc is used for Generator functions.
The return value of the function if an exception is not thrown in most cases (see contextValues).
This method provides a common interface for calling any ScriptFunction under the same compilation unit as the initial program. It should not be used to run "foreign" functions with a different const table. Use runProgram for that. This method may throw ScriptRuntimeException. Such an exception is caught at opNew and opCall boundaries and propagated or caught by the script.
