Find the first "living" object in the table of livings, that
has str as living name, set with set_living_name(). The the
object to search for must also have called enable_commands().
There is a special hash table that speeds up the search for
such living objects (thus you cannot rely on the order of
livings, if there are more than one with the same name).
EXAMPLE
object ob;
ob = find_living("Public Enenemy");
HISTORY
Since 3.2.1@40, this is a simulated efun. The handling of
living names is no longer part of the driver.
