This release adds reference closures which bind addresses containing values rather than simply pushing the values themselves, and adds proper support for double-cell values, including support for multiple double-cell values, and renaming 2bind, with-2closure, and 2closure-size to dbind, with-dclosure, and dclosure-size.
