docs: Get list of receivers from global tables
  
      This utility function allows you to retrieve the
      raw list of receivers from the connections table
      for the given sender and signal pair.
  
      Note:
          there is no guarantee that this is the actual list
          stored in the connections table, so the value
          should be treated as a simple iterable/truth value
          rather than, for instance a list to which you
          might append new records.
  
      Normally you would use liveReceivers( getReceivers( ...))
      to retrieve the actual receiver objects as an iterable
      object.
