2. I like your software but…
3. What sucks about Go?
4. Do you know about aspectj?
5. Really?
6. I’m not a code purist
7. “which is our full time job . write a program to write a program” - rob pike / gopherfest 2015
9. Go is Actually a Decent Fit
10. Prior Art go fmt go fix go generate
11. go fix
12. No Wrapping I don’t want to update code && leave the refs in it’s non-trivial I don’t want to hack it in/out each time I could forget in the future or not find all in the past
13. Aspect Contains behavior that is prominent in many places but don’t really have anything to do with your business logic. Logging is a canonical example.
14. Pointcut an expression that details where to apply your behavior CALL Before, after or wrap around calling a method. EXECUTE Before or after inside executing a method. WITHIN Every single call within a method.
15. Advice fmt.Println("Hello, 世界")
16. Logging
17. Monitoring
18. Performance Analysis
19. Debugging & Tracing
20. Undo Functionality
22. Behavior Mutation
23. Security
24. Transactions
25. Log every call to Itoa
26. Validation
27. Time Database Query Latencies
28. Ensure we log every panic in a goroutine
29. loom central place for storing .weave files you don’t have to re-invent the wheel more eyes - better software
30. it’s really
