Yes, I know about that site and the accolades heaped on Go for having it. 
Meanwhile, codepad has had it for years, and comeaucomputing has had it for at 
least 20 years now (for Comeau C++), and nobody cared.

I agree they do no harm, but once you're past the gee-whiz factor, they aren't 
of much use.
