  "message": "[Skylark] Speed up string.partition function.\n\nAccording to JMH using `ImmutableList.of` or `Arrays.asList` is ~2X faster\nthan using existing approach of creating an empty `ArrayList` with expected\nsize and populating it using `add` method. This is most likely due to extra\nrange and capacity checks.\n\nReturning `ImmutableList` instead of `ArrayList` avoids the need to copy it\nagain in order to create a `SkylarkTuple`.\n\nThese changes speed up the function by ~3X.\n\nCloses #5736.\n\nPiperOrigin-RevId: 207079605\n",
