Options bag parameter

[ghost]

How about, instead of the single second parameter, an "option bag" object is used instead for extensibility later?

ex:

function foo(callback) {
    try {
        callback( );
    } catch( cause ) {
        throw new Error( "callback threw an error", { cause } );
    }
}

This is duplicated with #10. I'm closing this.

I think it is not correct to dupe this with #10, since #10's original post is on a different, very large topic.

I'm reopening this issue since this is a smaller part of what #10 is intended to achieve. The option bag parameter is a very valuable alternative to the current positional parameter solution.
