Thanks. In w3mir, the following code:

my $thishost = hostname();
( my $name, undef ) = gethostbyname( $thishost );

Assigns $thishost to the Network Identity "Computer Name" of the Mac, which
is set by the File Sharing control panel. Your example makes perfect sense;
I'm trying now to make sense of hostname() and why it selects that name,
and what the original author intended.
