defer GoTime() (Go Time #112)

1 hour 4 minutes

Mat, Carmen, and Jon are joined by Dan Scales to talk about Mat’s favorite keyword in Go - defer. Where did the defer statement come from? What problems can it solve? How has it shaped how we write Go code? How are other languages solving similar problems? And what exactly was changed in Go 1.14 to improve the performance of defer?
