i need to decode a json string with a weird quirk....

# serialization

i need to decode a json string with a weird quirk. lists with only 1 entry omit the [] as if it was just a simple property of the inner type. eg x = listOf("foo", "bar") is serialized as "x": ["foo", "bar"] (as expected), but x = listOf("foo") is serialized as "x": "foo" instead of "x": ["foo"] . this breaks the parser, because it sees a x: String property where x: List<String> is expected. how do i work around this?
