How to pass a default value to a Go method if the language doesn't have function overloading?

Hello everyone! I just started learning Go after Python and encountered an unexpected problem. In Python, I'm used to writing functions with default arguments, for example: ```python def greet(name, greeting="Hello"): print(f"{greeting}, {name}!") ``` If you call `greet("Alice")`, greeting automatically becomes "Hello".

In Go, I tried to write it like this: ```go type Config struct { Address string Timeout int } func NewClient(address string, timeout int) *Conf
