I don't think that's true - .collect[Vec[u8]]() - here you might be accessing property collect and taking the value at index denoted by the item of Vec at posit

I don't think that's true - .collect[Vec[u8]]() - here you might be accessing property collect and taking the value at index denoted by the item of Vec at position denoted by the variable u8. And at the end calling the resulting thing? (That's not actually valid in rust afaik, you'd have to wrap it in parentheses like this `(...collect[])()`)

That is actually valid Rust, and it works exactly as you said: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=dd960239ede4419f4beeaadd35cec434 https://play.rust-lang.org/?version=stable&mode=debug&editio...

The argument that generics should have used [] generally goes hand in hand with the argument that [] for panicking indexing is a wart on Rust's "pit of success" design philosophy and that panicking indexing should have been more verbose to type than the .get() for Result-returning indexing... but probably less verbose to type than the `unsafe`, potentially UB-inducing `.get_unchecked()`.
