I am by no means an expert (or even a frequent user) of go. However, the most unfortunate foot cannon I have encountered is this: package main
type HowOdd interface {
Poke() string
}
type AConcreteThing struct {
}
func (t *AConcreteThing) Poke() string { return "hehe" }
func DoAConcreteThing() *AConcreteThing {
return nil
}
func DoAThing() HowOdd {
return DoAConcreteThing()
}
func main() {
lolWhat := DoAThing()
if lolWhat != nil {
panic("How could this happen?")
}
}
I understand that the interface at the bottom is a non-null interface containing a null value, but...damn, that sucks. |
