// Description : A named event, possibly with parameters. Anyone in
// any thread may throw an event at any time; there will
// be one process responsible for reading and dispacting
// on the events (but not necessarily immediately).
//
// This function use to inherit from Namable, but that
// makes it too expensive to get its name the Python
// code. Now it just copies the Namable interface in.
