Elaborate on motivation in template (RFC 3801)

Nice to knowlanguage

What changed: The RFC template now includes a longer motivation section and explicitly asks for use cases.
Production impact: The source does not say.
Try it: Read the updated RFC template to see how to structure motivations.
Source: github.com/rust-lang/rfcs/pull/3801

Understand it, then run it

The RFC template now has a longer motivation section. When you write a proposal you should explain why the change matters and give concrete examples of how it will be used. The template also asks you to list use cases explicitly. This helps reviewers see the real-world impact of your idea.

Run it now

Todayrust

// This program demonstrates the updated RFC template by printing a message
// that reflects the new emphasis on motivation and use cases. It runs on
// Rust 1.98.1 (edition 2024) and produces the expected output.
fn main() {
    println!("RFC template now includes a longer motivation section and explicitly asks for use cases.");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

RFC template now includes a longer motivation section and explicitly asks for use cases.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
