Parentheses in Decorators

[ghost]

1 function actuallyTransfer(from, to, amount) {
2 // do something
3 }
4
5 var invokeTransfer = once(maybe(actuallyTransfer(...)));

Should this perhaps be written as once(maybe(actuallyTransfer))(...)? To the best of my understanding, the decorators once and maybe should take in a function rather than a value.
