I apologise for the digression. However, there is some relevance, because asking for not just a new function, but a new opcode, suggests you have a use case that is both common and performance critical; apologies if I've missed it, but have you actually said what that use case is? > Pardon my ignorance, but what is exactly increasing the language complexity? Do you mean the addition of a language construct to the parser? Notice that Nikita said "conceptual language complexity", not "implementation complexity" - regardless of how simple this is in implementation, it's one more thing to document, maintain, and answer questions about.
