   Given the following Ink, I expect Inky to print "We are in the start knot", but it produces "End of Story" immediately when it reaches ~ listen(...).

   Does this mean we cannot use Inky to write and test when EXTERNAL functions are used?

   EXTERNAL listen(knot_name, event)
   
   ~ listen("encounter_win", "win_event")
   
   -> start
   
   === start ===
   We are in the start knot
   --> END

   You can. But you need to define a fallback - an inky-only version of the function (which might replicate that functions behaviour, or do nothing, depending on your needs). However, ink should report if there isn't one, rather than failing without a report.
