To make an asynchronous Observer would require quite a couple more tweaks, = allowing the Observer task to save its entry parameters and use them once t= he computation is over. In particular, the output channel should be passed = by access, rather than by in out value. This does not, however, void my core point that Ada's accessibility rules w= ould end up getting in our way if we wanted to implement something like Rea= ctiveX for Ada.
