----------------
Can an `Expr` has a parent too? If yes, why not invalidate the parents in `Import(Expr*)` ?
I am also a bit concerned to call the invalidation during the import of all `Stmt` (and possible during the import of `Expr`s too).
Isn't it enough to invalidate only during `Import(Decl*)`?
