In Go, you could pass a method value around so that the method can be
invoked later on a pre-determined receiver, e.g.
func (a *A) foo() bool { ... }
func bar(f func () bool) {
if f() {
...
}
}
func main() {
a := &A{ ... }
bar(a.foo)
}
You could also create a method expression so that the receiver can be
supplied at actual call time, e.g.
f := (*A).foo
boolVal := f(a)
But I couldn't find a way to bind a receiver to a method expression, such
that the resulting method value can be invoked at a later time. Would this
be a useful addition to the language? Or did I miss something?
