Hi Larry,

Currently, Symfony distinguishes between these sorts of events as you said,
by providing mutable or immutable event objects. If an event object is
immutable, the event is clearly an "info" event. If the event object is
mutable, it would be an "alter" event.

For example, GetResponseEvent [1] in HttpKernel is an "alter" event,
while PostResponseEvent [2] is an "info" event.

I don't think you need a more sophisticated pattern than that.

Cheers,
Bernhard
