trait FuncLike[W <: Term with Subs[W], +U <: Term with Subs[U]] extends Term with (W) => U with Subs[FuncLike[W, U]]
Terms that are functions or dependent functions, is a scala function, but the apply is not directly defined - instead the method FuncLike#act is defined.

Abstract Value Members
- abstract def act(arg: W): U
the action of the function to define: define this method, but use apply.
- abstract val depcodom: (W) => Typ[U]
- abstract val dom: Typ[W]
- abstract def newobj: FuncLike[W, U] with Subs[FuncLike[W, U]]
A new object with the same type, to be used in place of a variable to avoid name clashes.
A new object with the same type, to be used in place of a variable to avoid name clashes. Should throw exception when invoked for constants.
- Definition Classes
- Subs
- abstract def subs(x: Term, y: Term): FuncLike[W, U]
substitute x by y recursively in
this. - abstract val typ: Typ[FuncLike[W, U]]
the HoTT-type of the term
Concrete Value Members
- def :->[V <: Term with Subs[V]](that: V): Func[FuncLike[W, U], V]
constructor for (pure) lambda functions, see lmbda
- def :~>[V <: Term with Subs[V]](that: V): FuncLike[FuncLike[W, U], V]
constructor for (in general dependent) lambda functions, see lambda
- def =:=(rhs: FuncLike[W, U]): IdentityTyp[FuncLike[W, U]]
equality type 'term = rhs'
equality type 'term = rhs'

- def apply(arg: W): U
application of the function: use this but define the act method; checks HoTT-type of argument is in the domain and throws exception if it fails.
- def applyUnchecked(arg: W): U
- def canApply(arg: W): Boolean
checks if application is valid; can override to allow for example resizing universes

- arg

- returns
whether the argument has the correct type.

- def replace(x: Term, y: Term): FuncLike[W, U] with Subs[FuncLike[W, U]]
refine substitution so if x and y are both of certain forms such as pairs or formal applications, components are substituted.
