[rust-dev] how to call closures stored in struct slots (a 0.5 question)

In 0.4, I had a struct that stored a fn that I later called as if it were a
method. In 0.5, this has ceased. what is the new syntax for calling
functions stored in slots?

Here's the small code example (please excuse how naive it is):

https://github.com/stevej/rustled/blob/master/lazy.rs#L28

and here is the 0.5 compiler error I receive:

lazy.rs:28:21: 28:33 error: type `lazy::Lazy<'a>` does not implement any
method in scope named `code`
lazy.rs:28         let result = self.code();

Thanks,
Steve
