Implements default import method for modules
The Exporter module implements an import method which allows a module to export functions and variables to its users' name spaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimized for the common case.
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.
