I agree the interface is flexible, well documented and low-level, but the use of call-backs is something which is not immediately easy to understand, especially not for someone who is rather new to Perl and/or this type of programming. Hence, I call it "arcane" in the meaning of "obscure". I have to look-up the docs every time I want to use File::Find, there are too many "global" variables which contain all kinds of information some of which are to be read-only, others act as flags, ...

File::Find::Rulen as a wrapper around File::Findn brings its interface nicely within the more familiar procedural or OO-environment.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
