I think this is a neat idea.  However, there is a discussion whether
we want `yank-function' that takes over whole `yank' operation or
`yank-insert-function' that replaces only `insert-for-yank' part of
`yank'.  `insert-for-yank' is the one that actually strips off the
undesired text properties.

I prefer later from `table.el' application point of view but the
former is more generic and flexible.  But then that flexibility
involves the relationship with command replacement which is out of the
scope of this discussion.
