Re: Trying to compare a string...

[moritz]

In addition to choroba's excellent answer, I'd like to point out that you can replace code with data like this:

my %genre_map = (
    'Science Fiction' => 'Sci-Fi & Fantasy',
    'Sci-FI'          => 'Sci-Fi & Fantasy',
    'Fantasy'         => 'Sci-Fi & Fantasy',
    'Action'          => 'Action & Adventure',
    ...
);

my $genre = $genre_map{$genres[0]} // $genres[0];

Factoring the code like this would even allow you to put the genre mapping into a configuration file, and load the hash from it.

Finally, Perl 6 has a feature called junctions which does allow you to write code similar to what you tried:

use v6;
my $genre;
my @genres = 'Kids', 'Ignored';
if @genres[0] eq 'Science Fiction' | 'Sci-Fi' | 'Fantasy' {
    $genre = 'Sci-Fi & Fantasy';
} elsif @genres[0] eq 'Action' | 'Adventure' | 'War' {
    $genre = 'Action & Adventure';
} elsif @genres[0] eq 'Kids' | 'Family' {
    $genre = 'Kids & Family';
} else {
    $genre = @genres[0];
}
say $genre;
