List::Slice - Slice-like operations on lists
version 0.003
use List::Slice qw( head tail );
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 (...)[x] syntax.
my @values = head $size, @list;
Returns the first $size elements from @list. If $size is negative, returns
all but the last $size elements from @list.
@result = head 2, qw( foo bar baz );
# foo, bar
@result = head -2, qw( foo bar baz );
# foo
my @values = tail $size, @list;
Returns the last $size elements from @list. If $size is negative, returns
all but the first $size elements from @list.
@result = tail 2, qw( foo bar baz );
# bar, baz
@result = tail -2, qw( foo bar baz );
# baz
