Hi Leszek, Thank you for your reply. However, I believe the code examples you gave are not correct, as the same script unit will result in multiple script ids (e.g. one for the ScriptContext, others for top level function literals, etc).
Is there some way of tying all the code compiled from a single script unit / <script> to a single identifier?
