You could cherry-pick the later reverted

    Issue 4068: Add a convert-ly rule for xxx #'yyy #'zzz = -> xxx.yyy.zzz =
    
    Alist assignments can also use symbol list syntax as of issue 3748.
    So the examples for nested layout variable assignments should actually
    use those.

and start from there.  I think I considered this rule too sloppy to keep
it around permanently but then having nothing does not seem like a good
idea either.

So polishing this thing might be a good start.
