Another question: In the matcher do we support list of enums?

"request": {
    "states": [
      "matching(equalTo, 'ENUM_VAL_1')"
    ]
  },

I’m getting this error --- is it because enum is not added to should_be_packed_type?

Failed to match the request message - BodyMismatches({"$.states": [BodyMismatch { path: "$.states[0]", expected: Some(b"ENUM_VAL_1"), actual: Some(b"0102"), mismatch: "Expected and actual field have different types: 1:(states, Varint, Enum) = ENUM_VAL_1 and 1:(states, LengthDelimited, Unknown) = 0102" }]})

Good question. Mind raising a bug/feature request on the github repo?
