=over =item unshift ARRAY,LIST X Does the opposite of a L|/shift ARRAY>. Or the opposite of a L|/push ARRAY,LIST>, depending on how you look at it. Prepends list to the front of the array and returns the new number of elements in the array. unshift(@ARGV, '-e') unless $ARGV[0] =~ /^-/; Note the LIST is prepended whole, not one element at a time, so the prepended elements stay in the same order. Use L|/reverse LIST> to do the reverse. Starting with Perl 5.14, an experimental feature allowed L|/unshift ARRAY,LIST> to take a scalar expression. This experiment has been deemed unsuccessful, and was removed as of Perl 5.24. =back
