I'll be honest -- I hate working without a debugger. Go's gdb support was never great, and the team appears to have decided it's a fool's errand. On the other hand, the Delve project looks like it's serious about building a "real" debugger for Go (https://news.ycombinator.com/item?id=8595407). Supposedly it works on Linux, but I'm waiting on Mac support, which I understand is held up on Linux/Mach/Darwin differences.

In the meantime, I've gotten pretty good at printf() debugging (I worked on embedded systems in a past life, so it's a skill I've had to develop). I'm also considering adding some more structured log/trace/metrics stuff (perhaps exposed via a simple web UI) that would allow me to escape the "tyranny of the ever-scrolling console".

But in the end, I'll consider Go dead for game development (at least for me) if the debugger situation doesn't get fixed. I'm just betting that it will.
