Your code claims 'abc' is a palindrome.

$test = $palindrome is an assignment. Wrong!
$test == $palindrome is a numerical comparison. Still wrong!
$test eq $palindrome is a string comparison. Good.
lc($test) eq lc($palindrome) is a case-insensitive string comparison. Bingo!

Perl's operators are documented in perlop.
