@feersum Looks like the intent was to find a golfy ruby way, but the wording didn't mention golfy so technically it's off topic. If the author reads the latest comment they can edit if they want to, but I wouldn't feel comfortable editing based on an assumption

@Pavel What does boost have that C++17 doesn't

@Downgoat Python

(seriously the number one reason I use boost)

Oh, and I don't know exactly what C++ 17 has, but I don't think it has asio

Zacharý

Does boost have <variant>

DJMcMayhem

Yes

Pavel

@Downgoat As far as I can tell (please correct me if I'm wrong), boost::process's very simple io redirection.

Which is the reason I'm using boost

@Zacharý C++ std has variant

@Pavel C++ is super safe. Just -D_GLIBCXX_DEBUG -fsanitize=undefined.

@DJMcMayhem If you get * and & wrong, it's usually compiler error.

Actually the reason why C++ compiler gives a lot of template error is because it can't guess what you want.

@feersum We should ask OP whether they intend to do that first, before actually edit it to be on-topic.

codegolf.meta.stackexchange.com/a/14840/69850 ~

@trichoplax Same for me.

Although I don't feel like rollback it either.

Ok, I rolled back anyway. Somebody may want to lock it.

3:44 AM

@user202729 Why would you do that?

In the closed state there is no chance that the OP or the community gains any benefit from the question.

As a tips question there is.

user202729

Because we are not sure what OP intend.

feersum

Who cares?

user202729

If you want, you can (and should!) make another post.

feersum

Either they indent to ask a tips question or it is off topic.

Now that is even more rude.

user202729

I don't see how.

(OP may see 2 edit notification and get confused)

@feersum ("intend", not "indent")?

@Zacharý Can't D export global variable or something? regex Number = Number_()?

Zacharý

@user202729 It probably can, but I'm definitely fine with the way it is now!

user202729

Having to call a function to retrieve a constant value is weird.

It's a value, not a function, right.

Zacharý

Yeah, f() can be f. I memoized a function w/o parameters, which is definitely a bit hacky.

@gÓEûùIÿ Definitely not unclear. Still not try to solve it, so I'm not sure about the difficulty.

gÓEûùIÿ

It took me about 8 minutes to find a solution. But I might not be the best measure of difficulty because I'm already familar with the system.

Have you tried the practice examples?
