Ast_iterator.iterator
allows to implement AST inspection using open recursion. A
typical mapper would be based on Ast_iterator.default_iterator
, a trivial iterator,
and will fall back on it for handling the syntax it does not modify.type
iterator = {
iterator
record implements one "method" per syntactic category,
using an open recursion style: each method takes as its first
argument the iterator to be applied to children in the syntax
