It wasn’t necessarily a warning to you :) It comes from the days of GC bashing in Java and so everyone tried to manually write garbage free programs using pools and it had a bad effect on both performance and reliability. GC is there for a reason, use it... :) I would just hate to see Go developers “go” down the same path...
