parse_load_schema flag to not parse the schema

[AugustijnVrolijk]

Your idea

Hi All,

I've noticed that the schema returned by parse_load_schema is partially parsed. I've observed this with the expression_tests section where simple expressions such as "null", "false", etc... are interpreted into their pythonic counterpart.
This makes later interpretation more annoying as checks have to be introduced to see if an expression is a raw string or already parsed into something pythonic.
Is this something not changeable in yaml.safe_load()? (found in parse_load_schema() -> Namesapce.from_directory() -> _read_yaml_dir())
Possibly changing yaml.safe_load() to yaml.compose_all() ?

Thank you
