I for one look forward to an endless stream of "X support in Go" and "Y reimplemented in Go" posts over the next few years.<p>And judging from the last 20 years of programming language evangelism/flame wars, I completely expect to see "X support in AnotherLanguage" and "Y reimplemented in AnotherLanguage" posts followed up by "How AnotherLanguage is so much better than Go" and "AnotherLanguage vs. Go."<p>Sadly, what we'll never see is a retrospective along the lines of, "Did we waste all our time reinventing the wheel in AnotherLanguage?"
