> Identifiers can now contain non-ascii characters. All valid identifier characters in Unicode as defined in UAX #31 can now be used. That includes characters from many different scripts and languages, but does not include emoji. Don't despair fellow emoji devs, our time will come soon enough.

In the English speaking world, I have a hard time justifying untypeable identifiers. Maybe, and this is a fat maybe, Greek symbols could make the odd write-once math or scientific code easier to read. It would be bonkers to use any non-ascii codepoints in a public API.
I like to use the poop emoji in the names of methods that are dangerous hacks that we want to (eventually) get rid of. Being harder to type is part of the point.

maybe we can have some keyboard plugin/"mode" that merges letters to form symbols in special way? Korean windows have a "special-emoji" keyboard that can be invoked by: 1. type a charactor 2. press 'hanja' key 3. (wild special character selection menu appears) example: § (from 'ㅁ') / ㈜ (from 'ㅁ') / ㎖ (from 'ㄹ')
Should one learn Rust, lets say after 3-4 years, i.e by mid 2020s, once it becomes more mainstream? The syntax of Rust is a mix of OCaml/C++ and I feel some of the concepts are very esoteric for a normal enterprise Java/C#/JS/Python developer, so it takes a lot of cognitive overload to master it. So is it worth learning now or later?
This appears like it may happen with Rust but I hope it doesn't. It's a good thing it won't ever happen with Haskell, which is my warm safety-blanket should any particular language community implode.

> I feel some of the concepts are very esoteric for a normal enterprise Java/C#/JS/Python developer This notion is common among those who are first considering Rust, but also quite overblown in practice. The only thing that reasonably qualifies as "esoteric" in Rust is borrow checking and lifetimes, and these can be mitigated by using very simple idioms/patterns like cloning objects via .clone() or using copy-on-writ…
Disagree - a low level language can’t really mask itself as high level, the abstraction will always leak. Don’t get me wrong, Rust is a really great language and it is a very welcome addition to the for a long time seemingly stagnant low level world, but you won’t be able to refactor logic-related parts “without a thought” on memory layout, even ownership, etc —- something trivially done in high level languages. C++…

You can spend the time on it since you will make it up by not having to worry about your awful C++ dependency/build system which is the language targeted by rust to replace (/complement) ;)
Do you recommend it for those developers not working in the C/C++ space?

For many, learning the low-level aspects of programming is the attraction of learning Rust. They want to be exposed to these concepts. What Rust does well is creating a golden pathway with guard rails through which one can learn these concepts without exposing oneself to the pitfalls of memory safety issues, thread safety issues and undefined behaviour.

Can't you just use poop emoji in comments and search for them like TODOs?

* ALT e' = é
* ALT u " = ü
* ALT n ~ = ñ
It's not limited to diacritics; you can type ligatures (ALT ae = æ), extended characters (ALT [/] = ), I assume the majority of UTF (ALT #G = 𝄞) and so on. And yes, even emoji (ALT ALT alembic = )
edit: apparently, HN won't show the checkbox (U+2611) or alembic[1].
