[Message part 1 (text/plain, inline)]
The "load" function could do more of the right thing in the case where an
absolute path is given in a load call and then within the file loaded,
require or load references are made to relative files whose directories are
not in load path but the files do exist within the directory specified by
the original load.
So for example, we have a testing directory, "/tmp/" not in load-path with
files a.el and b.el.
In a.el, there is the line: (require 'b) and then we do a (load
"/tmp/a.el"). The require of b will fail but since load-file-name is set
to /tmp/a.el, if no matches are found in load-path, it would be a simple
matter to try to resolve b in the directory specified in load-file-name as
a fallback.
This would help in many cases when experimenting with new directories of
code that have not yet been added to the load path. It also would help the
Emacs package system since it adds only the top-level directory of a
package to load-path when trying to byte-compile the package. If the
package contains subdirectories, which require or load local files within
these subdirectories, these will fail right now but would succeed with the
above change.
Any comments, suggestions or issues with this? Please consider
implementing this and help make multi-directory packages a reality.

That package is here:
https://github.com/rocky/emacs-load-relative
But integrating the key points into "load" would be much more useful and
cleaner.

It's an interesting idea, and I guess it's pretty trivial to implement?
That is, if `load' is called with an absolute path, then bind
`load-path' and add the directory to the value locally.
It sounds convenient, but also kinda chaotic -- if I load "/tmp/foo.el",
then I may not want to load anything else from "/tmp/" just because
"/tmp/foo.el" says "(require 'bar)". That is, it sounds kinda insecure.
There's also the issue of being consistent -- today,
'(load "/tmp/foo.el")' and `C-x C-f /tmp/foo.el RET' and then
`eval-buffer' gives the same result... but this wouldn't be the case if
we changed `load' this way.
Now, we could add a new command `load-file-with-directory' or something
that would do this -- that would be more clear, at least, that we're
playing games with `load-path', and would be almost as convenient as if
`load' did this itself.
Any opinions here?

Nobody had any opinions here in a year, so I think the conclusion is
that we don't want to do this, and I'm closing this bug report.
