Sorry, importing.

I mean something like this

builtins.listToAttrs
map (x : { name = x; value = callPackage x { name = basenameOf x; }; }) 
(builtins.ls ./)
should allow me to export all main kde modules without explicit listing.

And some more magic (for recursive traversal) should replace `find . ...`-
generated files like /etc/nixos/nixos/modules/module-list.nix.
