Overview
Go allows associating arbitrary behavior with built-in or custom types, which contributes to the object-oriented character of the language. Note that Go is not a fully object-oriented language, it misses type inheritance, for example.
Syntactically, the association of behavior with a type is done by declaring a function (the behavior) and adding to it a receiver type (the type).
func (t T) FunctionName(parameters, ...) (return_types, ...) {
...
}
As result of this association, the function becomes a method of the type.
