> Today the user must explicitly provide any coders needed for serializing state data. We'd rather use the coder registry and infer the coder.
> Currently all factory methods in {{StateSpecs}} take a coder argument. For example:
> {code}
> StateSpecs.value(coderForT);
> {code}
> We could leverage the coder registry and provide different overloads:
> TypeDescriptor:
> {code}
> StateSpecs.value(typeDescriptorForT); 
> {code}
> Reflection:
> {code}
> StateSpec.value();
> {code}
