 //!
 //! #### Statements
 //!  - Assign statements work via normal Rust assignment.
-//!  - [`Retag`] statements have an associated function.
+//!  - [`Retag`], [`StorageLive`], [`StorageDead`], [`Deinit`] statements have an associated function.
 //!
 //! #### Rvalues
 //!
 //!  - Operands implicitly convert to `Use` rvalues.
 //!  - `&`, `&mut`, `addr_of!`, and `addr_of_mut!` all work to create their associated rvalue.
-//!  - [`Discriminant`] has an associated function.
+//!  - [`Discriminant`] and [`Len`] have associated functions.
+//!  - Unary and binary operations use their normal Rust syntax - `a * b`, `!c`, etc.
+//!  - Checked binary operations are represented by wrapping the associated binop in [`Checked`].
+//!  - Array repetition syntax (`[foo; 10]`) creates the associated rvalue.
