There are tied hash packages that implement object naming
and message passing between named objects within the same
process.  The packages allow invocations like:

  $msg{'desktop,paint'} = 1;
  $msg{'name entry,value'} = 'J. K. Cohen';
  $active_flag = $msg{'active checkbox,value'};

The packages also do broadcasting to subsets of the object
dictionary.  Hash stores and fetches are sent to or taken
from all the objects that match the supplied name.  So to
clear the value of all objects that have 'entry' in their
names:

  $msg{'entry,value'} = '';
