It is indeed most unfortunate that legacy standards such as XID_Start and XID_Continue unicode properties prevent the use of perfectly cromulent and inclusive symbols such as emojies. Fortunately, at least we can get a partial workaround using even more ancient text standards, e.g. egyptian hieroglyphs. This is valid Rust code:
let ๐ = 1u32;
let ๐ฃ = 2u32;
let ๐ฌ = 3u32;
let ๐ธ = vec![๐, ๐ฃ, ๐ฌ];
let ๐ซ = ๐ธ.into_boxed_slice();
let ๐ญ = ๐ซ.len();
You just need to disable pesky uncommon_codepoints lints.
If you think that all the good stuff was in the past and they just don't make languages like the old ones anymore (just look at chinese, gosh! that's what I call a bloated language!), you can use the simple and natural cuniform from a more civilized age:
let ๐ฉ = 1u32;
let ๐ฏ = 2u32;
let ๐ = 3u32;
let ๐
= vec![๐ฉ, ๐ฏ, ๐];
let ๐ณ = ๐
.into_boxed_slice();
let ๐ซ = ๐ณ.len();
Even a child can write that one! And they said COBOL was archaic ๐ ๐ฆ
The learned ones may prefer something more exquisite, with subtle artistic expression in the stroke of every symbol:
let ๊ฆ = 1u32;
let ๊ฆฏเทฏ = 2u32;
let ๊งฎ = 3u32;
let ๊ฉถ = vec![๊ฆ, ๊ฆฏเทฏ, ๊งฎ];
let ๊ฌค = ๊ฉถ.into_boxed_slice();
let ๊ = ๊ฌค.len();
Ah, Unicode! You're a real treasure tr๊ฎve of beautiful artisanal code!
