+\emph{Currying} is an operation that returns derivative of the function that has given value applied to its first parameter.\footnote{Do \emph{not} believe in that this is \emph{the} definition of currying. In the wild, currying is applied to cascades of \lambda-expressions and the behaviour is different to \tbas{}'s, even though it seems equivalent if you compare the function that two curries would produce.} See \ref{currying101} for tutorials.
