  Random thoughts :

  NewFind->file() instead of ->type('file')
  NewFind->name( '*.mp3', '*.ogg' ) to get a shorter 'or' condition (in this case, can be written as NewFind->name( qr/\.(mp3|ogg)$/ ))
  Provide an ->exec( \&command ) hook, similar to the -exec option to find(1) : i.e., gets the pathname as its only parameter, returns true or false.
  Think about -prune and finddepth.

    Yes, I was being very literal in a transliteration of a find(1) example, apart from making it longer of course.

    NewFind->name( '*.mp3', '*.ogg' ) to get a shorter 'or' condition (in this case, can be written as NewFind->name( qr/\.(mp3|ogg)$/ ))

    I like both of those.

    I still think there's need for a form of or. I just can't think of a good example right now.

      You still need an explicit or when your conditions are not on the same variable. The form shown here works for var == val1 or val2 but not var1 == val1 or var2 == val2. For example, file is greater than 500M or older than 3 days.

        I'm sorry, I don't follow. var == val1 or val2 seems to be like name('*.mp3', '*.ogg') and var1 == val1 or var2 == val2 is:

        # files greater than 500M or older than 3 days
        F->or( F->size( '>500M' ),
               F->age ( '> 3 days' )
             );

        As in rafaels "Good example for 'or'" post

          Yes, you followed what I was saying. I was giving an example where you have to have an explicit F->or method.
