this is very exciting b/c it feels like one of the 1st language features centered around runtime debugging.
Most languages don't seem to do a lot for run-time debugging. Being able to `gdb` and step-through on a local binary is a far-cry from detailed metrics / visualizations. We end up resorting to stuff like Honeycomb, but I'm waiting for the days of a programming language built for the ground-up for runtime debugging.
Anyways, this feels like an important step in the right direction and I'm excited to try this out
Go also has pretty good out of the box profiling (pprof[0]) and third-party runtime debugging (delv[1]) that can be used both remotely and local.
These tools also have decent editor integration and can be use hand in hand:
