final class TypeSig extends AnyRef
A type signature. This is a bit limited in what it supports right now, but can express a set of base types and a separate set of types that can be nested under the base types (child types). It can also express if a particular base type has to be a literal or not.

+(other: TypeSig): TypeSig
Combine two type signatures together.
Combine two type signatures together. Base types and child types will be the union of both as will limitations on literal values.
