Is it considered as too much work to > implement? Is that a question for me? If so, a predicate where, in what context? As I mentioned, the current uses of the regexp, in Dired+ as in vanilla Dired, are just to pass to `directory-files' as the MATCH argument. There are also Dired+ and Dired functions that accept a predicate as argument. `diredp-get-files' `diredp-get-subdirs', and `diredp-files-within', for example. What is it that you'd like to do/suggest? Or are you asking something about the predicate of this thread?
