Additional Guidelines

• Acronyms: Use Uuid instead of UUID (PascalCase), and is_xid_start instead of is_XID_start (snake_case).
• Numbers in Names: Use version_10_latest (for snake_case) and Version10Latest (for PascalCase).
• Single-Letter Words in snake_case: Use btree_map instead of b_tree_map, but pi_2 instead of pi2.
