thanks! In my case I have decided to write a new load-function,
which knows about the library etc. Then I don't think that
I need to go to the level of single functions, but I just
say "load file (if needed)" or "load file (in any case)",
where the first case is the default, and used in the library-files
(while the second case is needed if I need to reload a changed
library file into a running session).
That new load-function keeps a database of loaded files.
