+# By the time this is called, the record has already been physically
+# fetched from the server in the correct syntax, and placed in the
+# result-set's cache. But in order to actually get hold of it from
+# that cache, we need to set the record-syntax again, to the same
+# value, otherwise ZOOM will make a fresh request.
+#
+# ZOOM::IRSpy::Task::Retrieve sets options into the connection object
+# rather than the result-set object (because it's a subclass of
+# ZOOM::IRSpy::Task, which doesn't know about result-sets). Therefore
+# it's important that this function also set into the connection:
+# otherwise any value subsequently set into the connection by
+# ZOOM::IRSpy::Task::Retrieve will be ignored by ZOOM-C operations, as
+# the value previously set into the result-set will override it.
+# (This was the very subtle cause of bug #3534).
