MapPattern with Int() key not working with compound value

See original GitHub issue

I’m trying to write a schema using integer keys for a MapPattern, but am running into a snag:

from strictyaml import MapPattern, Int, Str, load, Any

yaml = """
1:
- ABC
2:
- DEF
- GHI
"""

schema1 = MapPattern(Str(), Any())
schema2 = MapPattern(Int(), Any())

print(load(yaml).data)
print(load(yaml, schema1).data)
print(load(yaml, schema2).data)  # fails

Result:

OrderedDict([('1', ['ABC']), ('2', ['DEF', 'GHI'])])
OrderedDict([('1', ['ABC']), ('2', ['DEF', 'GHI'])])
Traceback (most recent call last):
  File "<untitled>", line 16, in <module>

  File ".../Python3.7/strictyaml/yamlpointer.py", line 179, in get
  File ".../Python3.7/ruamel/yaml/comments.py", line 753, in __getitem__
KeyError: '1'

Am I doing something wrong or are Int() keys not supported?

No, that looks like a bug, and quite an embarrassing one too 😦

I’m going to prioritize fixing this today.

Hi, it’s proving to be a little trickier than I thought to do this but I’m still working on it. Thanks for your patience.
