I use &function_name for writing to multiple files. So if I have: 
sub write_log {
 ...
}

sub write_error {
 ...
}

Instead of placing the following in my script: 
write_log('string');
write_error('string');

[download]
I can keep it cleaner by simply having: 
write_all('string');

[download]
With write_all defined as: 
&write_log;
&write_error;
