This is the highest and most important thing I want from go. A proper debugger that is not insanely hard to setup ( on any machine! ). Gives a complete stack trace and such info. I am not sure how people can live without a debugger in 2014. GDB is not the answer to this - for sure. There are soo many things that can be done ( tooling wise! ) and this one is , I personally think, the first things the golang guys need to do .
