That would be a strange assumption. It's important that DIRECTORY can
be used to traverse directories. If I want to have truenames, I can
just call TRUENAME or perhaps PROBE-FILE on the results of DIRECTORY.
But I can't call anything else to traverse directories besides

I shouldn't need to install third party libraries just to list the files
in a directory.
