Factory Method Pattern

[Mike Mikhailov]

Factory Method Pattern in Go is function which returns an interface (something what is implementing an interface)... that's all. This means you should not think about this pattern and use a pattern when you known patterns. You should make only a function like func NewXXX(arguments) <interface> {...} for your needs (or in ideal case package.New()). And every gofer are making this everyday. And it is not a pattern. This is Interface builder or Interface constructor as you like.
I affirm that Go does not require knowledge of any patterns (as OOP requires), but it requires an understanding of SOLID principles and having a mind.
