On page 143, you note that the '!' operator is a logical operator when in fact it is an "operator to derefence mutable reference cell" (http://www.markhneedham.com/blog/2009/04/25/f-not-equalnot-operator/).

Re: Page 143: logical operators
yes - you're of course right. The "!" operator (for working with reference cells) is actually discussed in chapter 8, I just didn't realize that when categorizing all the allowed operator characters in chapter 6. It looks like I'll have to move it to the "other characters" category!
