print "$fields[0] fields1"; That's not going to cause a bareword error under strict.
Why? Especially $^W? Note that my @fields should be parenthesized to get a list... Why? Under what circumstances does the declaration of an array not provide list context? while ( defined( my $line = <$data> ) )defined is unnecessary here because Perl will add it for you. ... also, you opened $data, so don't forget to close it. The filehandle's stored in a lexical variable and it's the end of the program and you're not bothering to check the return value (for a filehandle opened for reading!), and the filehandle's at the end of the file at this point, and you have autodie in effect, so why bother?
