 * We prefer portable Go, not assembly. Code in assembly means (N packages * M architectures) to maintain, rather than just N packages.
 
-* Minimize use of assembly. We'd rather have a small amount of assembly for a 50% speedup rather than twice as much assembly for a 55% speedup. Explain the decision to place the assembly/Go boundary where it is, and support it with benchmarks.
+* Minimize use of assembly. We'd rather have a small amount of assembly for a 50% speedup rather than twice as much assembly for a 55% speedup. Explain the decision to place the assembly/Go boundary where it is, and support it with benchmarks in the commit message.
 
-* Explain the root causes. What changes in the compiler and standard library would allow you to replace this assembly with Go? (New intrinsics, SSA pattern matching, other optimizations.)

 * Make your assembly easy to review; ideally, auto-generate it using a simpler Go program. Comment it well.
