It isn't efficient but it allows you to simplify your code. Without generic
pointers multiply functions, doing the same thing, are needed. Like *printf*vs.
*printf_P*. Needing multiply functions that do basically the same thing also
adds overhead. Generic pointers for the smaller AVR's would only need 16/24
bits.
