* \@keypath allows compile-time verification of key paths. Given a real object
126+
* receiver and key path:
127+
*
128+
* @code
129+
130+
NSString *UTF8StringPath = @keypath(str.lowercaseString.UTF8String);
131+

// => @"lowercaseString"
138+
139+
* @endcode
140+

141+
* ... the macro returns an \c NSString containing all but the first path
142+
* component or argument (e.g., @"lowercaseString.UTF8String", @"version").
143+
*
144+
* In addition to simply creating a key path, this macro ensures that the key
145+
* path is valid at compile-time (causing a syntax error if not), and supports
146+
* refactoring, such that changing the name of the property will also update any
147+
* uses of \@keypath.
