Yeah it's on one line and looks elegant. Unfortunately there is no error control and it skips directories with a leading '.' in the name (e.g. '.foo', '..bar').
  1. From perldoc File::Glob: 
    The POSIX defined flags for bsd_glob() are:

"GLOB_ERR"
    Force bsd_glob() to return an error when it encounters a directory
    it cannot open or read.  Ordinarily bsd_glob() continues to find
    matches.

  2. Skipping directories with a leading dot may be a feature. One can glob '.*' if need be.
Not to say that there are not situations in which an explicit opendir & C. is actually preferrable. Indeed there are. My point being that in the vast majority of cases a simple glob would do instead. I think OTOH it has a stigma due to the fact that anciently it relied on a call to an external shell, which is what I read it in a book, but since I don't have effective experiennce with Perl 4, the last one that I think was set up like that, I cannot tell for sure...
