18 - **Would you consider yourself a novice, intermediate, or experienced Go programmer?**
19 - **What other languages do you have experience with?**
23 - **Has this idea, or one like it, been proposed before?**
24 - **If so, how does this proposal differ?**
25 - **Does this affect error handling?**
26 - **If so, how does this differ from previous error handling proposals?**
27 - **Is this about generics?**
28 - **If so, how does this relate to the accepted design and other generics proposals?**
32 - **What is the proposed change?**
33 - **Who does this proposal help, and why?**
34 - **Please describe as precisely as possible the change to the language.**
35 - **What would change in the language spec?**
36 - **Please also describe the change informally, as in a class teaching Go.**
37 - **Is this change backward compatible?**
38 - Breaking the Go 1 compatibility guarantee is a large cost and requires a large benefit.
39 Show example code before and after the change.
42 - **Orthogonality: how does this change interact or overlap with existing features?**
43 - **Is the goal of this change a performance improvement?**
44 - **If so, what quantifiable improvement should we expect?**
45 - **How would we measure it?**
49 - **Would this change make Go easier or harder to learn, and why?**
50 - **What is the cost of this proposal? (Every language change has a cost).**
51 - **How many tools (such as vet, gopls, gofmt, goimports, etc.) would be affected?**
52 - **What is the compile time cost?**
53 - **What is the run time cost?**
54 - **Can you describe a possible implementation?**
55 - **Do you have a prototype? (This is not required.)**
