=head1 SYNOPSIS

    use List::Slice qw( head tail );

=head1 DESCRIPTION

This module provides functions for slicing lists. This is helpful when you

want to do a chain of manipulations on a list (map, grep, sort) and then

slice, without the cumbersome C<(...)[x]> syntax.

=head1 FUNCTIONS

=head2 head

    my @values = head $size, @list;

Returns the first C<$size> elements from C<@list>. If C<$size> is negative, returns

all but the last C<$size> elements from C<@list>.

    @result = head 2, qw( foo bar baz );

    # foo, bar

    @result = head -2, qw( foo bar baz );

    # foo

=head2 tail

    my @values = tail $size, @list;

Returns the last C<$size> elements from C<@list>. If C<$size> is negative, returns

all but the first C<$size> elements from C<@list>.

    @result = tail 2, qw( foo bar baz );

    # bar, baz

    @result = tail -2, qw( foo bar baz );

    # baz
