My comment about 20 years was in response to a quote from the parent comment. But yes, that's a very good point. Very few languages have ever come out of the gate close to the mark. Early C# and Java were painful without closures, iterators, function pointers, or good performance. Which is why I'm glad to see things like TypeScript, Closure, and ES6, Traceur, etc. (and I'm less excited about Coffeescript and Dart). It's especially a good sign that Google is using TypeScript as a basis because it means we might not get siloed implementations and communities.
