Real programmers try stuff. There's nothing about this question you couldn't answer for yourself just setting up the conditions you describe so clearly. Why make others do your work for you? Try it and let us know what you learn. — matt 13 secs ago

Why is an error necessary? How can anyone expect anyone to use this language if even experienced programmers are left helpless without a compiler to tell them how the language works? This must be the simplest question to ask about cloning and closures, and yet no one seems able to say anything useful without talking to their compiler. No one knows Rust, it seems. Only the compiler does. — Test 23 secs ago

@Scooter have you tried debugging the code yet? Debugging is an essential skill that all programmers need. If you don't know how, this is a good time to learn. — Remy Lebeau 19 secs ago

@Zeitounator, I fail to see how questions on Jenkins (a continuous integration tool used in the SW development process) are a better fit on superuser (Q&A for computer enthusiasts and power users). The 49000 vs 290 jenkins tag ratio would seem to make that a consensus, unless/until you can convince S/O to migrate most similar questions there. Why isn’t this question suited for Stack Overflow?| Not about programming or software development | Use this close reason if the question is not about ..., or software tools primarily used by programmers. Agree the OP should provide more context. — Ian W 56 secs ago

This isn't a programming question. It's also not possible, thank goodness. Otherwise unscrupulous programmers could make users run arbitrary code without their knowledge. — Panagiotis Kanavos 21 secs ago

Don't do this. A singleton will last for the lifetime of the application. In case of a web application, the lifetime of the web server. You would have to restart the web server to get the new instance. Other reasons: Is it a bad practice to use Singleton for DI in Asp.net rather than Scoped, Transient whenever possible? — kkuilla 53 secs ago

Follow up: I believe when a function is imported the entire module is always imported, so I am not sure this functionality is possible. softwareengineering.stackexchange.com/questions/187403/… — Joseph 44 secs ago

@jcalz I have added input and output examples, thanks for your feedback! It doesn't make sense to give examples of compile errors because I was just trying out every crazy piece of syntax that came to my mind - that's what we programmers do when we want to get something working quickly in an unfamiliar new programming language :) — frangulyan 53 secs ago

Aside, std::monostate can also be used like a unit type as found in some other languages. (Those other languages may use the term monad, which to C++ programmers is a lot like saying "it" to the Knights Who Say Ni! To demystify monad: a monad is a function that takes one parameter and returns one result. Nothing to be scared about. Monad-centric languages only allow monad functions. That may be a bit scary.) — Eljay 57 secs ago
