After talking with Ed in private, I realized that I must have misunderstood the situation. He was mainly curious about how to satisfy existing functionality in gdb and lldb. He didn't mean to convey that he would block the merge of the patch. I must have misunderstood. I still dislike the feature, but it'll remain in the patch upstream. I fear that I may be growing tired of non-technical discussions involving politics. As I said to Adrian Chadd in IRC, over the last nearly two years, I've kissed so many shoes to get this in, I've now grown weary and cynical. Unless someone has actual technical input regarding the patch itself, I'm going to refrain from commenting further. If you have technical input regarding the patch, please comment on the diff at Phabricator.
