The never type (!) can coerce into any other type, allowing expressions like return or break to serve as values in assignments, conditions, and match arms.
Assignment expressions return unit (()), enabling chained assignments, comparisons, and tuple patterns to work on unit values.
Control flow keywords such as break, continue, and return can be used as expressions inside loops, if conditions, and match statements due to their never type.
Range syntax (.. and ..=) can be arbitrarily combined to form complex range types, all of which implement Debug for formatting.
Grouped use statements with nested braces reduce boilerplate and support unlimited levels of nesting in imports.
Rust allows recursive module re-exports, permitting infinitely nested module paths by reusing weak keywords in declarations.
Unicode identifiers and raw identifiers (e.g., r#match) enable using keywords and special characters as variable and function names.
Fully qualified function pointers and explicit generic turbofish syntax let you pass trait methods and functions anywhere a Fn type is expected.
