Unfortunately I think print is one of the built-ins that can't be overloaded (though I don't recall where I read this). You don't state why you want to overload it but you can probably accomplish what you want using Filter::Handle to intercept output to filehandles (including STDOUT and STDERR).

For example, the following snippet is pulled from one of my programs. The filter sub does 2 things: 1. if it sees any text that matches a password, it replaces it with xxxxx (that means I can dump config info to a log file for debugging but not worry about sensitive data being strewn about) and 2. It prints a copy of everything sent to STDOUT and STDERR to a log file.

use Filter::Handle qw(subs);
Filter \*STDOUT, \&filter_sub;
Filter \*STDERR, \&filter_sub;

sub filter_sub
{
    #sub for Filter::Handle
    #filter out the password if we see it so password doesn't get stre
+wn all over log files
    local $_ = "@_";
    my $pass = $config{password};
    s/$pass/xxxxx/g;  
    #write everything to logfile then to pass to filtered file handle
    print LOGFILE $_;
    $_;
}
