Sort::Key::Top::PP - pure Perl implementation of parts of Sort::Key::Top
use Sort::Key::Top::PP 'top'; my @top5 = top 5 => @biglist;
Sort::Key::Top::PP is set of functions for finding the top "n" items in an array by some criteria. It's not as fast as Sort::Key::Top, but it is generally quite a bit faster than sorting the entire array and taking the first "n" items.
This module implements pure Perl equivalents of the following functions as descibed in Sort::Key::Top.
By default all functions are exported. If you don't like that, then please specify an explicit list of functions to import, a la:
use Sort::Key::Top::PP 'top';
Please report any bugs to http://rt.cpan.org/Dist/Display.html?Queue=Sort-Key-Top-PP.
