Done.

Do we need this yet?

[nasko, 2013/05/30 17:07:03]

Not yet, but it made the pattern of constructing the object very intuitive. If
you feel strongly this shouldn't be there yet, I'll remove it.

[Charlie Reis, 2013/05/30 18:26:59]

I just don't want people (myself included) to think we can start using this
value, since we're not updating it.  It's fine to pass it into the constructor
and do nothing with it, but let's not keep it as a member until we're ready to
keep it up to date.

Done.
