Just to play devil's advocate, here's what that example would look like with exceptions and something like `using()` in C# (here, any curly block can implicitly be treated like a try block, like in Ruby):

    package main

    import (
        "io"
        "log"
        "os"
    )

    func cat(name string) {
        using (f := os.Open(name)) {
            io.Copy(os.Stdout, f)
        }
    }

    func main() {
        for _, arg := range os.Args[1:] {
            cat(arg);
        } catch (err os.Error) {
            log.Print(err)
        }
    }
