  Yeah, I thought about doing a "nice" version of File::Find myself. I wanted to tie in a few things as well - the ability to get structured data as well as lists from it, and to cache data.

  I'm not sure I like the stream-y interface you've got here - powerful, but violates the KISS principle which makes File::Find such a pain in the arse to use at the moment. I'd pictured more of a hash-based interface, but I hadn't thought of options so much (but I guess they could be done either by regexps or arrays).

    I'm not sure I like the stream-y interface you've got here - powerful,

    I wasn't either, hence the posting, but then I saw Rafael's beautiful "Good example for 'or'" for which powerful is certainly one of the words I'd use.

    By stream-y I assume you mean the chaining of method calls? If you don't like it you can always do it in longhand:

    my $f = NewFind->new();
    $f->name( '*.mp3', '*.ogg' );
    $f->size( '<10000' );
    my @potayto = $f->find('.');
    
    my @potahto = NewFind->name( '*.mp3', '*.ogg' )

      The notation of chaining method calls like that is an unfamiliar one to me at least (see, told you I was crap), and probably to the target audience of the module (viz. those who find all those icky callbacks in File::Find too tricky).

      As for the tree, I envisaged some kind of structure depending on what parameters you pass to the find involving some quantities of stat()ing etc., thusly:

      $VAR1 = {
            name => '.',
            path => '.',
            abspath => '/home/richardc',
            type => 'directory',
            children => [
                  {
                    name => 'music',
                    path => './music',
                    abspath => '/home/richardc/music',
                    type => 'directory',
                    children => [
                          {
                            name => 'S Club 7 - Party.mp3',
                            path => './music/S Club 7 - Party.mp3',
                            abspath => '/home/richardc/music/S Club 7 - Party.mp3',
                            type => 'file'
                          }
                                ]
                  },
                  {
                    name => 'Procul Harum - A Whiter Shade of Pale.ogg',
                    path => './Procul Harum - A Whiter Shade of Pale.ogg',
                    abspath => '/home/richardc/music/Procul Harum - A Whiter Shade of Pale.ogg',
                    type => 'file'
                  }
                        ]
          }

      Basically enough information to reconstruct the file list but letting you walk the tree structure.
