I'm not sure if they are sufficiently similar, but there are other use
cases for something like this. For example, I recently wanted to extend
`next-error' to find flymake highlights.

An idea I had was to replace/extend `next-error-function' with a hook
where the first non-nil return value is used as the location of the
next error.
