-pre encoders are functions of arity 1 that pre-process input to the encoder. only input evaluated in a *value* context is pre-processed in this manner (so keys are not pre-processed, but objects and lists are). if more than one pre encoder is declared, the input will be passed to each of them in the order they are declared
