Title: Partialised Functions
Version: 0.1.1
Description: Provides a 'partialised' class that extends the partialising function of 'purrr' by making it easier to change the arguments. This is similar to the function-like object in 'Julia' (https://docs.julialang.org/en/v1/manual/methods/#Function-like-objects).
