I use &function_name for writing to multiple files. So if I have:

sub write_log {
 ...
}

sub write_error {
 ...
}
[download]

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;
[download]
