invoke macro in the Indirection section

[Michael O'Keefe]

Loving the book so far! Thank you for writing it.

In the chapter on Indirection, there is a macro for invoke. Question: shouldn't that macro pass the object x as an argument to the method implementation?

Perhaps something like:

(defmacro invoke
 [class->method->impl x method & args]
 `((get-in ~class->method->impl [(class ~x) ~method])
    ~x ~@args))

Where the second to last element (before ~@args) is the new part?

Sincerely,

Michael O'Keefe

Yes, it should. That was an oversight on my part, thank you for catching it.
