Enum Event #	The Enum instance may not be very efficient, but it should hardly be used, at all. Better use constants such as `inp` and set manipulation. If the binary logarithm is computed by constant unfolding, performance would be better, but direct set manipulation is still faster. We implement the `Enum` instance in this way, in order to stay independent from the particular Poll definitions, that may differ between platforms.
