proc_use_inline is a Rust crate offering an alternate syntax for mod and use
statements. Take the following Rust code:
```rust
mod foo;
use foo::*;
use itertools::*;
mod ext;
This literally translates into:
rust
procmacroinline::procmacroinline! {
#[mod]
use foo::*;
use itertools::*;
mod("../other/ext.rs");
} ```
