Hi I've been programming in perl for quite some time now, and it's the first time I've run into this construct before, looking at the source code for Net::FTP (https://perldoc.perl.org/Net::FTP.txt): 
   ${*$ftp}{'net_ftp_host'}    = $host;       # Remote hostname
   ${*$ftp}{'net_ftp_type'}    = 'A';         # ASCII/binary/etc mode
   ${*$ftp}{'net_ftp_blksize'} = abs($arg{'BlockSize'} || 10240);

As far as I know, "*" is a typeglob representing $ftp %ftp @ftp and ftp, but why are they using that here? Shouldn't the code just say $ftp->{'net_ftp_host'} = $host; ?
