Description
This is a big handwave, but it would be super-useful if there were some way to show inferred types and lifetimes. It would be very useful for learning/teaching/exploring code samples.
I don't know what tech exists to enable this - perhaps RLS integration?

Research direction
The issue does not identify files, tests, or an entry point. Start by investigating whether RLS integration can expose inferred types and lifetimes in the Rust Playground, then define a concrete user-facing approach and acceptance criteria for code samples.
