--  This child package of Sinfo contains some routines that permit in place
--  alteration of existing tree nodes by changing the value in the Nkind
--  field. Since Nkind functions logically in a manner similar to a variant
--  record discriminant part, such alterations cannot be permitted in a
--  general manner, but in some specific cases, the fields of related nodes
--  have been deliberately layed out in a manner that permits such alteration.
