will help you In definition of t2 you are trying to "extend" type t1 which is not completely defined at this point (as it requre t2 in `A branch).
If you want to "emulate" recursive ordinary data types (but using polymorphic variants instead) you should use all references to mutually-recursive types under data constructor.

I wish did fix the issue. I have the class Variable[X <: SeqVal[_]](initialState:Calc[X]) , Here's the code I tried compiling:
code :
trait SeqVal[T]
trait Calc[T]

class Variable[X <: SeqVal[_]](initialState: Calc[X])

case class Max(seq: Int = 0, value: Float = .0f)
    extends SeqVal[Float] with Calc[SeqVal[Float]]

object test {
    new Variable[SeqVal[Float]](Max())
}

fixed the issue. Will look into that further No, you cannot "build" a new native type, not without (of course) patching the compiler to extend the language. At that point you're no longer working in standard C (nor C++), but some extension thereof.
The point of C and C++'s native types is to express a decent approximation of what typical CPU hardware can do, at a native level. You can't expect to "go beyond" that in terms of types without expecting to do the work, i.e. implement the abstraction.

will help you During deserialization JsonDeserializer needs to create the object first and then populates it with data. It will use the default parameterless contrusctor for that. It obviously cannot create the object. Check, that you can actually create your object, i.e.:
code :
GetSystem getSystem = new GetSystem();

Any of those help The error message is correct. There is no public constructor available for Table class. You can confirm that on MSDN: Table Class.
