According to http://perldoc.perl.org/perlopentut.html: "Indirect filehandles also make it easy to pass filehandles to and return filehandles from subroutines."

Okay, so how do I find out which file this filehandle references? If the file name is dynamically generated, and all I have is a filehandle, how do I know which file is being written into?

For example: 
#get a filehandle 
$fh = get_fh_from_file( generate_filename() ); 

if ( print_data( $fh, $data ) ) {
  say "data printed to file: $fh"; 
}
## got: data printed to file: *TRSC::FileUtils::FH;
## expected: '/path/to/file'
