Page 110: SimpleString is referred to incorrectly as being of type "string" in the parenthetical sentence.

[WraithGlade]

The following text:

(It’s your responsibility as a user of string to check for this condition.)

... should instead be this:

(It’s your responsibility as a user of SimpleString to check for this condition.)

Hi @WraithGlade, I think this could go either way: string refers to the object in Listing 4-16 while SimpleString refers to its type. I'll make the change for clarity's sake. Thanks!
