I want to do this:

open (FILE,$file); # $file is a |-delimited file
my @header = ('h1','h2','h3'); # I already know the headings
my %values; # make a hash of hashes to remember the values

while (<FILE>) {
  chomp;
  my @columns = split /\|/;
  my $unique = $columns[1]; # h2 is the unique identifier
  @values{$unique}{@header} = @values;
}

[download]

... but I get a Can't use subscript on hash slice error. Is there a good way to do this without doing it "manually?" I can think of several ugly ways to do it. I know @values{@header} = @columns; works, so I assume it will work for a more complex hash.
