Immediately Initialized should be Immediately Invoked

[ychaikin]

On page 404, it states:

Manually implement a module design pattern as an immediately initialized function

I believe, it should say "as an immediately invoked function".

Thanks. We put it correctly in Chapter 2, but not in the Appendix. It's too late to fix in the printed version, but I'll send submit this correction in the book's errata when available.
