That looks nice and simple.

As I said, the dir scanning was just an example of recursiveness.
Still, I do need to scan a directory in a way that I get an array of
files per each block call, and not one file at a time, because I want
to compare the contents of a directory with other directory, in order
to identify changed files, new files, deleted files, etc.
