   @blackdrag this is the other alternative I alluded to in earlier comments. No change to `GString`, `GStringImpl` enhanced slightly with a flag that enables defensive copy in/out for the string and value arrays. We create GStrings in @CompileStatic code with that flag set. Caching is only enabled when that flag is set and values are simple immutables. This piggy-backs on the idea that @CS turns off "dynamic behaviors" even though mutating those arrays is a bit of a stretch of what constitutes dynamic behavior.
