But we have already started project 1. Code from project 1 will be used throughout the semester. I'd postpone this to next semester.

`From` is implemented on concrete types (I32Array, Utf8Array, etc.) instead of the generic `Array` trait. Therefore, you have to use macros to expand them instead of calling it on traits.

部分学院有奇偶页页眉要求，如果您所在的学院对奇偶页眉没有要求可以自行修改。

选课备注已经有了，放假信息需要等等

Probably I'll get some easy-to-reproduce examples...

The difference: ``` INFO rustc_trait_selection::traits::query::normalize normalize::: result=Ok(fn(futures_async_stream::try_stream::from_generator::GenTryStream) -> std::pin::Pin {::boxed::` after `boxed`. Not sure if this is the contributing factor of so many obligations... still working on a minimum reproducible...

Not related to futures_async_stream. Need investigate where are the 4000+ obligations from. cc @xxchan let's close for now until we find the root cause and submit another issue?

Probably has fixed by https://github.com/rust-lang/rust/pull/102945? Let's try again. Nope 🤣

We need to consider two cases: * How to handle holidays? * How to handle courses that occur at 3, 5, 7, 11 weeks? If these could be easily handled...

LGTM to me. I'll add this support sometime later.
