This belongs in the "The Good" section ;)

Go has composition, which is much better than inheritance. Your example can be much simpler by the way:

type Node struct {

tag int

}

func (n Node) getTag() int {

return n.tag

}

type FunctionDefinition struct {

Node

}

Now you can call getTag() on an instance of FunctionDefinition.

Edit: Well, I'm trying to get this in a code block in order to get it more readable, but I can't get it to work.
