# Create a list palindrome
my @l = <A B C B A>;
# Reverse the list (see P05)
# Then compare it
#       ==      This will compare two lists, and return true if they contain the same
#       elements - but it does not care about the order of the elements.
#       eq  This will turn the list into a string, and compare those
