Errors parsing yaml lists of dictionaries

[sg3-141-592]

Tested using niet ==3.2.0 and python 3.11.1

When trying to parse dictionaries that are in a list we get an error

niet -f eval . test.yaml

hello:
  world:
    - abc : 123
    - def : 456

Traceback (most recent call last):
  File "/workspace/.pyenv_mirror/user/3.11.1/bin/niet", line 8, in <module>
    sys.exit(main())
             ^^^^^^

Hello,

Thanks for reporting this issue and sorry for the late reply.

I think the error is related to the presence of the dash in lines with abc and def.

If I remove these dashes, then, the error disappear:

$ tox -r -e venv -- niet -f eval . /tmp/test.yaml
...
venv: commands[0]> niet -f eval . /tmp/test.yaml
hello__world__abc="123";hello__world__def="456"
.pkg: _exit> python /usr/lib/python3.12/site-packages/pyproject_api/_backend.py True hatchling.build
  venv: OK (8.86=setup[8.76]+cmd[0.10] seconds)
  congratulations :) (8.99 seconds)

Is these dashes are mandatory?
