Research direction

Start by reading loop-expr.md and verify the stated restriction for the last expression of loop blocks such as loop and while. Check the surrounding Rust Reference text or relevant language behavior to confirm whether the restriction is correct. Done means loop block type behavior is accurately specified in loop-expr.md.

Written by the indexing model from the issue text.

Description

A-expressions

I think the last expression of loop blocks (loop, while, etc.) must be the unit type. If that is correct, it should probably be specified in loop-expr.md.
