this feels like a lot of cut and paste.
can we make this more succinct by parametrizing this on <scope, version> (e.g. <global, alpha>) etc so we only need to maintain one block of template text

Are you referring to the duplicate code in lines 210-239 and 247 to 275? Those are the same except the operation is Create vs Update. We are following the same pattern for RegionalDefault and GlobalDefault resources.

@spencerhance @bowei I have modified the template text to a single block for regional/global/zonal cases. PTAL, thanks.

// ToForwardingRuleList converts a list of compute alpha, beta or GA
// ForwardingRule into a list of our composite type.
func ToForwardingRuleList(objs interface{}) ([]*ForwardingRule, error) {
result := []*ForwardingRule{}

err := copyViaJSON(&result, objs)
if err != nil {
return nil, fmt.Errorf("Could not copy object %v to list of ForwardingRule via JSON: %v", objs, err)
return nil, fmt.Errorf("could not copy object %v to list of ForwardingRule via JSON: %v", objs, err)

We use the template variable substitution {{type.Name}} to generate this. Fixed it to use %T.

switch key.Type() {
case meta.Zonal:
default:
return fmt.Errorf("Key %v not valid for zonal resource NetworkEndpointGroup %v", key.Type(), key.Name)
