The representation of types is described below. When a type is defined on a given
connection between an [Encoder] and [Decoder], it is assigned a signed integer type
id. When [Encoder.Encode](v) is called, it makes sure there is an id assigned for
the type of v and all its elements and then it sends the pair (typeid, encoded-v)
where typeid is the type id of the encoded type of v and encoded-v is the gob
