Go1.5 尚未实现的Todolist

Go 1.5 code freeze is May 1, 2015; release is August 1, 2015. This is a list of things we’re hoping will be in Go 1.5 but are not yet done. For the list of things that are done, see doc/go1.5.txt. Strikethrough items are done. This list only lists “big” items. This list is only aspirational; it is not a promise or a contract. Comments? Mail golang-dev. Thanks.
