Net::FTP's constructor calls IO::Socket::INET, which calls IO::Socket, which in turn calls IO::Handle. And IO::Handle uses gensym to create the glob.

In other words, if you wanted to fake a (totally functionless!) object of same type, you could try: 

#!/usr/bin/perl

my $ftp = Net::FTP::Faked->new();

print "$ftp\n";   # Net::FTP=GLOB(0x63c430)


package Net::FTP::Faked;

use Symbol;

sub new {
    my $ftp = gensym;
    bless $ftp, "Net::FTP";
}
