Higher-order list utility functions

This module provides a number of list utility functions, all of which take an initial code block to control their behaviour. They are variations on similar core perl or 'List::Util' functions of similar names, but which use the block to control their behaviour. For example, the core Perl function 'sort' takes a list of values and returns them, sorted into order by their string value. The sort_by function sorts them according to the string value returned by the extra function, when given each value. my @names_sorted = sort @names; my @people_sorted = sort_by { $_->name } @people;
