When we were discussing about how introduce console events, I talked about the possibility of intercepting all events in order to include a new parameter. Now, using the console.command is possible to add such parameter but we can't retrieve its value.
I think it can be achieved introducing a pre and post bound event, where in the first we have the opportunity to append a new option and in the second retrieve its value and perform some action.
Seems like other users have the same use case and for now the only workaround is very ugly and not recommended.
