The thing I immedeatly liked about genera is that you have more than a
"default directory" when referring to filenames.

In Unix, you set a "current directory" and incomplete pathnames are
relative to it.

In Genera, you have a machine, a path, a filename, an extension and a
version component as a file's name.

All these have the default like the former pathname used. So, when you
had "mash:>some>dir>foo.lisp" as a previous file, you could say "bar"
and it would make "mash:>some>dir>bar.lisp" (not "bar" without
".lisp"), you could say ">otherdir>" and it would make
