-Here, \code{CF} is a curried function of \code{F}; built-in operator \code{$<\!\sim$} applies \code{32} to the first parameter of the function \code{F}, which dynamically returns a \emph{function} of \code{CF(T) = ABS(T) == 32}. The fact that Curry Operator returns a \emph{function} opens many possibilities, for example, you can create loads of sibling functions without making loads of duplicate codes.
