@camc314 In case you're interested, this relates to your question #9751 (comment). But this is a micro micro optimization. Only saves a couple of instructions, which is a drop in ocean. |

Micro-optimization. Re-order variants of `VariableDeclarationKind`. With this order: * Checking if it's a lexical declaration is `discriminant != 0` * Checking if it's const is `discriminant > 1`. The latter is a couple of instructions shorter than it was before (`discriminant == 1 || discriminant > 2`).
