I disagree. The real value of exceptions is you can skip 6 levels of functions that have lines like

status = DoThing(); if(status != allIsWell) {return status;}

C++ embedded for a long time has said don't use exceptions they are slow. However recent thinking has changed - turns out in trivial code exceptions are slow but in more real world code exceptions are faster than all those layers if checks - and better yet you won't give up on writing all the if checks. Thus embedded projects are starting turn exceptions on (often optimized exceptions with static pre allocated buffers)

The final "print something when wrong" is of little value, but the unwinding is very valuable.

For some reason some Go programmers think those lines are the best thing since sliced bread.

Do you have any references for that? I used to avoid exceptions on small Cortex M0/M3 devices as well.

Khalil Estell has some great work on that. https://www.youtube.com/watch?v=bY2FlayomlE is one link - very low level technical of what is really happening. He has other talks and papers if you search his name.

Nice, thank you!
