Thanks, that makes a lot more sense. My projects so far have included well under 1000 LOC of my code per page. If and when this changes, I will watch out for this issue and consider Closure Compiler as a possible solution. I also wonder if (runtime-checked) pre/post-conditions could bring much of the benefits you speak of, with the option to use them sparingly and avoid the "drag" part. In other words, make the type annotations optional and only put them where it looks like the extra safety is important enough to be worth it. In any case, I'll cross that bridge when I get to it. Thanks for the heads up.
