How small is the smallest .NET Hello World binary?
> I wonder if this could be used to make C# webassembly more viable.
You might enjoy reading this GitHub thread [0] where the community contributed a WASM library wrapping the C# regex code so that regex101.com could have a "C# mode". Lots of nerd sniping about reducing the payload size.
(There's also another thread [1] discussing the minification of a rust version of that same regex101 wasm library to provide a "rust mode" using @burntsushi's regex crate.)

[Media] Regex101 now supports Rust!
That’s correct, compiled to WASM. You can see all the nitty gritty here https://github.com/firasdib/Regex101/issues/1208

Regex101.com needs help getting a small Rust WASM binary
Excellent comparisons. ~150KB without unicode would make Rust the smallest wasm on Regex101 as far as I can tell. pcrelib comes in at 198KB. Personally, I think ~400KB with unicode features is just fine for .wasm size. The heaviest flavor C# is around 4.91MB and was added back in February of this year. They also had a performance comparison which would also be interesting.

Question regarding a Regular Expression
Ruby Regexp comes from Onigmo, so there is also Onigmo's doc. I noticed that the "backreference with recursion level" exists in Onigmo's doc but is missing from Ruby's doc.

>Ruby even supports Perl regular expressions
No, Ruby Regexp is based on the https://github.com/k-takata/Onigmo library. There are plenty of differences compared to Perl, for example `^` and `$` anchors always match start/end of lines without needing a flag, subexpression syntax uses `\g` instead of `(?N)` and so on.
