			* log, so you only need to provide a listener if you have some other console
			* (like Phabricator's DarkConsole) which you //also// want to send errors to.
			*
			* NOTE: You will receive errors which were silenced with the `@` operator. If
			* you don't want to display these, test for `@` being in effect by checking if
			* `error_reporting() === 0` before displaying the error.
			*
			* @param const A PhutilErrorHandler constant, like PhutilErrorHandler::ERROR,
			* which indicates the event type (e.g. error, exception,
			* user message).
			* @param wild The event value, like the Exception object for an exception
			* event, an error string for an error event, or some user object
			* for user messages.
			* @param dict A dictionary of metadata about the event. The keys 'file',
			* 'line' and 'trace' are always available. Other keys may be
			* present, depending on the event type.
			* @return void
