i hope it isn't a problem that my challenge pretty much demands big integer support, due to what it does

(Java is often shorter)

yeah, probably the most verbose programming language you could use in code golf

@dzaima i don't know, map is pretty much free in Java as long you require Stream<T> as a function argument

like tree::Map is shorter than std::collections::HashMap, but at the same time you need to declare a dependency in another file

i'm looking forward to Rust 2018, where you will be able to use external dependencies without using extern crate declarations, but at the same this is yet another tricky issue in terms of rules.

HashMap is like std::collections::HashMap however and it's not imported by default

@dzaima Okay, I suppose Rust also has ArrayList in prelude, as opposed to having to import java.util.*, but otherwise more verbose

to print the results

as i do println!("{:?}", f(10).collect::<Vec<i32>>());, where i specify i32 explicitly, not requiring me to specify the type for parse method

not sure if it's acceptable

i sorta depend on type inference later on in test code with parse here however

it is verbose, as i said

|n|(0..n).map(|n|format!("{}{}",n,n+1).parse().unwrap())

from 39 bytes to 56 bytes

it's 56 bytes now

yeah, i guess .. is nicer than IntStream, but literally everything else is more verbose

yeah, it's wrong

oh, i see

for a language more verbose than Java it's way too short, and i have a feeling i may have misunderstood something

can somebody verify whether codegolf.stackexchange.com/a/167882/3103 is a valid solution

okay, using an explicit block complains about variable not being effectively final (as it forces it to be a local variable)

i suppose it has to do with local variables being actually class static variables due to how Java REPL was implemented

which is nice, could shorten code golf programs (i wonder if that's a bug, but i mean, it's a feature)

oh, this is interesting, jshell doesn't require effectively final bindings for lambdas

Java 10's var isn't even a big deal as far jshell code golfing is concerned because there is Shift-Tab V combination for declaring variables

i sorta want to try more Java 9/10 codegolfing, because jshell has so much codegolf potential (especially due to keybindings)

5 bytes

although i recently posted a solution for Java 9, so dunno

although i suppose List.of, Map.of and Set.of is meaningful for codegolf

i sorta suspect it has to do with extremely short support period and rather minor improvements

although i think specifically saying "PHP 7.1" or whatever is fine, right?

disappointing, so a future version of PHP won't support unquoted strings

for instance, H[Tab] won't work, because Http classes

but also not so nice, because it means more conflicts when you tab, oh well

oh, it imports quite a lot, nice :)

|    import java.io.*
|    import java.math.*
|    import java.net.*
|    import java.nio.file.*
|    import java.util.*
|    import java.util.concurrent.*
|    import java.util.function.*
|    import java.util.prefs.*
|    import java.util.regex.*
|    import java.util.stream.*

it's Java REPL in this case, jshell

although i wonder if using REPL keybindings is a legitimate strategy

HashMap is Ha[Tab]M[Tab] (by the way it's cool that java.util is automatically imported)

i mean, you can write i[TAB] instead of int, for instance

i wonder if using a Tab key is a legit strategy for Java REPL codegolf however

quite boring honestly

or that exceptions don't have to be of Exception anymore which would affect set_exception_handler - unimportant for codegolf, no reason to use exception handlers for code golf

because changes like "you cannot name your classes int" are unimportant - you wouldn't call your classes int in code golf even if you could, when there are better names like A

i was going to say that PHP 7 wasn't that major from code golfing point of view, but then i realized it removed ereg and split functions

@Dennis sounds fair, then :)

And this feature is really useful for code golfing.

Is it possible to add PHP 7.1 to TIO.run? My reasoning is that using undeclared constant is deprecated in PHP 7.2 (and I think it will be removed in PHP 8).
