coding : i

[dc4ac@radiosocial.de]

@catsalad Actually, it's ѭ

[luc0x61@mastodon.gamedev.place]

@catsalad The all times favorite, thanks to math and K&R, can only be i, but... I do a lot of MISRA strict code, so nothing shorter than 4 char and meaningful in the context!

@catsalad U+037E

[ada@mastodon.catgirl.cloud]

@catsalad@infosec.exchange U+202E, the right to left override character "‮". it does what it says on the tin. (and also reverses parentheses)

I have a character in one of my books called Viva, and everyone abbreviates it to Vee, so...

As Rust developer, of course `_`

The Fortran people do. But we need the i in the first place

[ramonfincken@mastodon.social]

@catsalad i next to "temp" for a var that only lives 5 lines

[perlplayer@mastodon.social]

@catsalad $_

[ptmcg@fosstodon.org]

@catsalad It's not 1 but 2 characters: `_·` This is a legal variable name in Python. The second character is the Unicode MIDDLE DOT. It is only legal as a body character, not an initial character, so you need the leading "_".

[ptmcg@fosstodon.org]

@hcf @catsalad Sadly, Python rejects this. There are a limited number of leading characters for variable names (although Unicode denormalized versions of them are valid), but emojis aren't among them.
