It seems like only methods can be decorated. Is there any hope for decorators on top-level functions in the future?

  Unfortunately, due to hoisting decorating top-level functions is a real pain [1]. What should the behavior of: myMagicFunction(); var myDecorator = require('myDecorator'); @myDecorator function myMagicFunction() { // TODO: Make magic } be? - `myDecorator`'s require statement is hoisted above `myMagicFunction`'s declaration so that `myMagicFunction` is always decorated? (Results in a given `var`'s behavior changing depending on whether it is invoked as a decorator, an exceedingly non-obvious behavior) - Function hoisting doesn't happen for decorated functions (non-obvious, possibly hard to implement). - Function hoisting happens but the decorator is not hoisted (resulting in a sometimes-decorated function). These problems don't admit of a simple solution (at least as far as I can see). [1]: https://github.com/wycats/javascript-decorators/issues/4
