This seems like circular logic to me - extending the reader should
mean that new types can have read syntax. The problem here, I think,
is that the compiler also needs to know how to serialize those types.

Why don't we provide an interface to define a serializer as well as a
reader, and have compile-assembly use these serializers? As long as
each type has both a serializer and a reader, it should work fine.
That also feels symmetrical, which I take as a good sign. :-)
