Because global variables have a much simpler structure than constants, they're pretty easy to optimize. I had not done so up to JRuby 1.7.1 mostly because I didn't see a compelling use case and didn't want to encourage their use. However, after Tony Arcieri pointed out that invokedynamic-optimized global variables could be used to add logging and profiling to an application with zero impact when disabled, I was convinced. Let's look at the example from above again.
