What are you trying to achieve?
I am trying to use pkl to produce a json file that uses hypens in many property names.

What’s the impact of this bug/feature?
I cannot use pkl to produce this json file.

pkl --version Pkl 0.25.2 (Linux 5.15.0-1050-aws, native)

Test file

test {
        with-hyphen = "test"
}

Running pkl eval -f json file.pkl produces the following error:

No viable alternative at input `-hyphen =`.

Expected behavior

I would expect pkl eval -f json file.pkl to produce the following:

{
  "test": {
    "with-hyphen": "test"
  }
}

Thank you.

You can use backticks:

 `with-hyphen` = "test"

Thank you! I swear I tried everything but backticks.

Same applies BTW for keywords.
E.g

`function` = 2
