No problem at all. But I see a problem in that function require doesn't
behave as its documentation says it does. Or I just don't understand it,
which is worse.

OK, let's widen the picture frame.

I have 2 files: required.el and requiring.el.

required.el contains:

(defvar var1 "Value"
  "This variable is used by \"requiring.el\"")

Them, since requiring.el uses this variable, I write:

(require 'required)

expecting that "required.el" to be loaded at run time.

I'm afraid this is not the right approach. Perhaps both files should be
put together. Or use (load "required.el") instead. I just don't know.
