I don't understand why Apple recommends this. I find this naming convention
very convenient for accessor and mutator methods. Unlike with method names,
the compiler will warn you if you've overridden a variable with the same
name, so I don't see much harm in using underscores to prefix instance
variable names.

P.S. On the same page, Apple also recommends developers to "Explicitly
declare instance variables either @private or @protected." Do people really
follow that guideline? Most of the code I've read doesn't have access
specifiers for instance variables.
