I think it would be neat if a warning could be a simple string or a
cons where the car is the warning string and the cdr is a callback
that should be interactive (to be called via call-interactively):
Something like this: ("This foo should be a bar" . 'handle-foo-bar).

This way for warnings that can be assisted, a callback can be fired to
help the user to solve it. The "_emacs" to ".emacs" case is a good
example. Also is the case of deprecated vars.

The callback of course should let the user choose to take action or not.
