I'm afraid I don't really know, as I have virtually no experience in
CLOS.  Others on the list should know, though...

   Don't take it personally but it wasn't a compliment,
   if I would have done one I would have said "Thanks,
   it's a great example" or something like that ;)

Understood.

   Not at all, and I take it as another compliment.

Thanks.

   So it's a little bit different from mkdir -p givne
   that mkdir -p just create directories (at least under
   OSF1)

I didn't know about mkdir -p before.  mkpath also only creates
directories, like mkdir -p, but it ignores any part of its argument
after the last occurring slash.

   And I find it more easy to understand than map, just
   because the name "for-each" is easier to understand
   even for somebody that never saw it before (IMHO).

Yes, I agree, now that I know about it!
