// 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.
