I like the c style for loop syntax. Swift creator's decision of removing it doesn't make sense to me.
1. async function will be called from no async function but no async/await keyword. If you want to block main thread then block_main() function will be used. block_main() /* operations */ unblock_main()
2. protocol can inherit another protocol(s) & protocol can confirm a class like swift.
3. no `let`. only `var`. compiler can optimize further.
4. if (a == (10 || 20 || 30) || b == a) && c { }
5. `Asterisk` is replaced to `x` operator for mul operations.
What are the features you found or you need in a programming language?
