initially i had thought to use pid_to_list, but was discouraged from
using it because of the warning in the documentation: "This BIF is
intended for debugging and for use in the Erlang operating system. It
should not be used in application programs."

thanks for the reminder: i'd forgotten that, or rather, remembered it
elsewhere but not here. it seems best, then, to create a table that
stores symbolic name / PID associations, returning the former to the
thanks for your response.
