When using you last advice:
(setq load-path (cons "~/work/mylisp" load-path))
(load-file "setnu.el")

I get the error:
File error: "Cannot open load file", "/home/saneman/setnu.el"


Seems that the load-path is not updated.


The fist solution:
(setq mylisp "~/work/mylisp/")
(load-file (concat mylisp "setnu.el" ))

works. Are there any rules that say that .el files will not be found in 
the load-path?
