kotlinlang

i have a data structure that i serialize into a database using cbor. i want to change one of the fields on the data class from a `val foo: Foo? = null` to a `val foos: List&lt;Foo&gt; = listOf()` but leave all the other serialization logic alone.  any tips? i see the @KeepGeneratedSerializer stuff but can't figure out how to delegate to that deserializer only for this one field

or maybe there's some way i can just annotate that one field and use the old field name with a `@SerialName("foo")`...and then check the descriptor to determine if it's a list or a nullable? hmmm
