Support multiple trigger operations per one handler binding

[IlyaMatsuev]

What is missing from the application? Please describe.

Right now it's not convenient to bind a handler that has to be executed for different trigger operations. For example:

trigger SomeTrigger on SomeSObj__c(after insert, after delete, after undelete) {
    Triggers.IHandler someHandler = new SomeHandler();
    Triggers.dispatcher
        .bind(TriggerOperation.AFTER_INSERT, someHandler)
        .bind(TriggerOperation.AFTER_DELETE, someHandler)
        .bind(TriggerOperation.AFTER_UNDELETE, someHandler)
        .run();
}

Describe the solution you'd like

Would be good to have an opportunity to do something like this:

trigger SomeTrigger on SomeSObj__c(after insert, after delete, after undelete) {
    Triggers.dispatcher
        .bind(
            new List<TriggerOperation> {
                TriggerOperation.AFTER_INSERT,
                TriggerOperation.AFTER_DELETE,
                TriggerOperation.AFTER_UNDELETE
            },
            new SomeHandler()
        )
        .run();
}

So, I don't need to instantiate handler before binding
