Funktor


definition
  let x1 be Θ1;
   .....
  let xn be Θn;
  func (a1,...,am) ⊕ (am+1,...,ak) ->  Θ(x1,...,xn)
  means Φ(x1,...,xn,it);
end;

gdzie {a1,...,ak} ⊆ {x1,...,xn-1} oraz domknięcie zbioru {a1,...,am} ze względu na zależność typów daje cały {x1,...,xn-1}.

Funktor (a1,...,am) ⊕ (am+1,...,ak) służy do tworzenia termów (τ1,...,τm) ⊕ (τ1,...,τk).

Przykłady: x+y, Cl X, mmlquery
