fun <I1, I2, I3, I4, O> (I1, I2, I3, I4) -> O.memoize(): (I1, I2, I3, I4) -> O fun <I1, I2, I3, I4, I5, O> (I1, I2, I3, I4, I5) -> O.memoize(): (I1, I2, I3, I4, I5) -> O fun <I1, I2, I3, I4, I5, I6, O> (I1, I2, I3, I4, I5, I6) -> O.memoize(): (I1, I2, I3, I4, I5, I6) -> O Returns a locally-memoized version of this function. Two separate invocations of memoize will have two separate caches.
