I think I see.  By "leaf" I really meant "non abstract": both `symbol`
and `symbol-with-pos` describe *the* type of some objects (IOW `type-of`
can return that symbol), as opposed to things like `sequence`, `list`,
atom`, `number-or-marker`, ...

I see that `symbol` is missing there.  Don't know if that's why it
explodes, OTOH.

Better keep a few extra useless entries in there.
