Maybe you could also fix

/// This is a hard to find infinite recursion that will crash any code
/// using it.

by using something like "Infinite recursion in trait implementation will crash or loop forever, and are hard to find.". In the example, compiling in release mode will loop forever as the recursive call is transformed into a tail recursive one, while compiling in debug mode will crash because of a stack overflow.
