For # 1.5, I would just add `t.Helper()` as the first line of `handleDBConnection`.
For # 3, this is also sometimes called the "Builder" pattern, and if any of the steps could cause an error, but you still want the simplicity of chaining, you can add a `Build` or `Do` method at the end of the chain that returns one or more values, including a (potentially "joined") error (typically accumulated during the building of the chain).
No, Marcelloh, the idea behind using method chaining here is to improve code readability and conciseness. With method chaining, you can perform multiple actions on an object in a single line, like this:
Nice list, I've learned a few things, thanks! One question: the link https://medium.com/@func25/go-performance-boosters-the-top-5-tips-and-tricks-you-need-to-know-e5cf6e5bc683 is behind paywall, do you have a copy somewhere else?
Ah yes, I have edited it, here is the story: https://blog.devtrovert.com/p/go-performance-boosters-the-top-5
Very nice, thank you!

I use this builder pattern here, for example: https://github.com/gmlewis/go-bjk/blob/master/examples/bifilar-electromagnet/main.go#L155
Because you have pointer as method receivers:
func (p *Person) AddAge() *Person {
p.Age++
return p
}
func (p *Person) Rename(name string) *Person {
p.Name = name
return p
}:
You can do:
func (p *Person) AddAge() {
p.Age++
}
func (p *Person) Rename(name string) {
p.Name = name
}

No, Marcelloh, the idea behind using method chaining here is to improve code readability and conciseness. With method chaining, you can perform multiple actions on an object in a single line, like this:
```go
p.Rename("Aiden").AddAge().DoA(1).DoB(3)
```
Instead of:
```go
p.Rename("Aiden")
p.AddAge()
p.DoA(1)
p.DoB(3)
```
