Using the compiler we can write:
\begin{axiom}
)abbrev package MAPPK3C MappingPackage3c
++ Description: Higher-order Currying operations.
MappingPackage3c(A:SetCategory, B:SetCategory, C:SetCategory):_
  MPcat == MPdef where

    MPcat ==  with
        curryR:   ((A,B)->C) -> (B->(A ->C))
        curryL:   ((A,B)->C) -> (A->(B ->C))

    MPdef == add
        MappingPackage3(A, B, C)

        fabc: (A,B)->C

        curryR(fabc) == curryRight(fabc,#1)
        curryL(fabc) == curryLeft(fabc,#1)

\end{axiom}


\begin{axiom}
plus:(INT,INT)->INT
plus(x,y) == x+y
plusX:=curryL(plus)
\end{axiom}
