BUG: MapCombined documentation different traceback

[msftcangoblowm]

Environment:

• py39 (3.9.16)
• strictyaml: 1.7.3

strictyaml.MapCombined docs show a different traceback

Straight from the documentation

from strictyaml import Any, Int, MapCombined, Optional, Str, load

schema = MapCombined(
  {
    "required": Str(),
    Optional("foo"): Int(),
  },
  Str(),
  Any(),
)

yaml_snippet = """1: Hello World
not_an_integer: 42"""

load(yaml_snippet, schema)

Expected (shown in docs)

strictyaml.exceptions.YAMLValidationError:
when expecting an integer
found arbitrary text
in "", line 2, column 1:
not_an_integer: '42'
^ (line: 2)

Actual

strictyaml.exceptions.YAMLValidationError: while parsing a mapping
in "", line 1, column 1:
'1': Hello World
^ (line: 1)
required key(s) 'required' not found
in "", line 2, column 1:
not_an_integer: '42'
^ (line: 2)

Recommended action

• Confirm
• Update the docs (story)

The bigger question: How can the docs (story) be wrong?
