I add a suggestion for the async variant

[sigmaSd]

seems like there is a lot of code like this https://github.com/search?q=%2Fasync.*%5Cn.*Deno.*Sync%2F+language%3ATypeScript&type=code

[sigmaSd]

couple of notes

• this won't catch wrapped blocking function like function a() {Deno.readSync..} async function b() {a()}
• console.log is also blocking, there could be other functions ?
• rust issues https://github.com/rust-lang/rust-clippy/issues/4377 https://github.com/rust-lang/wg-async/issues/19
