We talk about the same thing, though I want to remove requirement of
using absolute paths in any function files. You wrote:

The point is to make <what-goes-here> not needed at all. The path is to
be taken from "dircache" (that's the name used in previous messages).
Autoload should use dircache of fun1 to find fun2, then follow to
process fpath. There can be an option to enable/disable this.

I've described how flexible and clean would be management of custom
version of functions this way. It's like having packages of software
instead of functions. Requiring the <what-goes-here> part will make this
difficult.

Thought about it, it's a cool approach.
