"""
A PyYAML loader that annotates position in source code.

The loader is based on `SafeConstructor`, i.e., the behaviour of
`yaml.safe_load`, but in addition:

 - Every dict/list/unicode is replaced with dict_node/list_node/unicode_node,
   which subclasses dict/list/unicode to add the attributes `start_mark`
   and `end_mark`. (See the yaml.error module for the `Mark` class.)
