    Pipe function. Takes an initial value and any number of functions/methods.
    Methods as strings. Additional args are supported for functions & methods
    by suppling a step as a tuple/list with function/method as the first
    element and the args as the rest. The pipe input is used as the last
    argument in this case. Currently no kwargs.
