on all nodes :
.is_statement, returning true if the node should be considered as a
statement node
.root(), returning the root node of the tree (i.e. a Module)
.previous_sibling(), returning previous sibling statement node
.next_sibling(), returning next sibling statement node
.statement(), returning the first parent node marked as statement node
.frame(), returning the first node defining a new local scope (i.e.
Module, Function or Class)
.set_local(name, node), define an identifier <name> on the first parent frame,
with the node defining it. This is used by the astng builder and should not
be used from out there.
