[go-nuts] Converting Panic into Error

[Henry]

Hi,

I would like to shield my application from any possible panicking by the 
third-party library. There was an occasion when a third party library 
crashed my application due to unnecessary panicking. I am thinking 
of creating a thin wrapper that will also catch any panic into error. How 
can I do that in Go? 

func PanicFunction() {
     panic("Panic!")
}

func MustNotPanic() error {
     defer func(){
          if err:=recover(); err!=nil{
               //ermm ... how do you return error from here?
          }
     }()
     PanicFunction()
}

func main(){
    if err:=MustNotPanic();err==nil{
         fmt.Println("Failed to catch panic")
         return
    }
    fmt.Println("success")
}

Thanks.
