The test_file patterns does not seem very powerful to me :
- for the most obvious cases, like filtering by extension, it can't be used
- for complex cases, you are limited by the number of test cases.
I think it could be easily remplaced by :

val filter : (Unix.stats -> bool) -> string list -> string list (** we are
clearly showing the dependency to unix here *)

Other things I would like to get added to the Filename module :

val extension : string -> string (* returns the extension of the file or ""
if no extension *)
val switch_extension : file:string -> ext:string -> string (* change the
extension of a filename *)
