trait Typ[+U <: Term with Subs[U]] extends Term with Subs[Typ[U]]
HoTT Type; The compiler knows that objects have scala-type extending U. In particular, we can specify that the objects are types, functions, dependent functions etc.
- U
bound on scala type of objects with
thisas type. in practice, it is symbolic objects of the type whose scala type is bounded.

Type Members
Abstract Value Members
- abstract def newobj: Typ[U] with Subs[Typ[U]]
A new object with the same type, to be used in place of a variable to avoid name clashes.
