Incorrect bullet point reference
Chapter 7: Concluding C# 2: the final features: P182, section 7.1.1
Last updated: 05/12/2011
The second paragraph on page 182 starts:
Only (1) specifies any type constraints, and only (3) specifies a base class. If (1) had specified a base class, it would have to be EventArgs, and if (4) had specified any type constraints they'd have to be exactly as in (1).
The (4) there should be a (3).
