TODO List for File::Util
Not necessarily listed in order of priority:
1)  [DONE] Set up formal (not just private) GIT repository
2)  [DONE] Separate documenation examples into a cookbook (POD)
3)  [DONE] Gradually transform methods to accept input parameters in a
    *::Class-like style (hashrefs, etc) while preserving backward compatibility
4)  Support for Perl IO "layers", which just hasn't been requested but
    should be there for completeness
5)  [DONE] Transform (where useful) various methods to accept callbacks.
    File::Util::list_dir() is the primary target
6)  [DONE] Set up File::Util::list_dir() to take a listref of regexes
7)  [DONE] Continue improving the distribution so as to make it compliant
    with Fedora packaging standards; it is already a maintained package for
    Ubuntu and ActiveState.
8)  [DONE] Code clean up in POD documentation examples.
9)  [DONE] Improve and simplify code examples in POD documentation.
10) [IN PROGRESS] Constantly improve test suite until Devel::Cover
    scores are something to be proud of.  We're doing much better
    than we used to only less than 1 month ago
11) [DONE] Remove all traces of old invocation syntax from the POD
12) [IN PROGRESS] Now that documentation has been divided into the ::Manual and
    the ::Cookbook, I want to add more content to them.  More examples,
    More fully-functional programs (recipes).
13) [DONE] Create a less-verbose Exception class (right now we only have
    Exception::Diagnostic, which is overkill for power users and "experts" who
    just want a quick, clean error message instead of a full-page printout of
    what went wrong, how to fix it, and whose fault it was -- followed by a
    callstack.  We need the less verbose alternative now.
14) Create a benchmark suite, plot and publish metrics as part of the
    documentation.
15) Memo-ize pattern "gathering" for recursive list_dir() calls for greater
    efficiency.  Right now there's a gather op for ever recursion, and that
    just isn't necessary.  That can be optimized out.
16) Provide an option to follow symlinks in list_dir(), and keep track of
    inodes seen while traversing directories to avoid filesystem loops
17) Try to get unicode-on-windows support for filenames, which is actually
    a Perl-core issue.  I might/might not be able to fix that.
