继续-优雅地处理多个错误？

Question

Is there a way to clean up this (IMO) horrific-looking code?

    aJson, err1 := json.Marshal(a)
bJson, err2 := json.Marshal(b)
cJson, err3 := json.Marshal(c)
dJson, err4 := json.Marshal(d)
eJson, err5 := json.Marshal(e)
fJson, err6 := json.Marshal(f)
gJson, err4 := json.Marshal(g)
if err1 != nil {
    return err1
} else if err2 != nil {
    return err2
} else if err3 != nil {
    return err3
} else if err4 != nil {
    return err4
} else if err5 != nil {
    return err5
} else if err5 != nil {
    return err5
} else if err6 != nil {
    return err6
} 

Specifically, I'm talking about the error handling. It would be nice to be able to handle all the errors in one go.

var err error
f := func(dest *D, src S) bool {
    *dest, err = json.Marshal(src)
    return err == nil
} // EDIT: removed ()

f(&aJson, a) &&
    f(&bJson, b) &&
    f(&cJson, c) &&
    f(&dJson, d) &&
    f(&eJson, e) &&
    f(&fJson, f) &&
    f(&gJson, g)
return err
