 # Statements and expressions
 
-Rust is _primarily_ an expression language. This means that most forms of
-value-producing or effect-causing evaluation are directed by the uniform syntax
-category of _expressions_. Each kind of expression can typically _nest_ within
-each other kind of expression, and rules for evaluation of expressions involve
-specifying both the value produced by the expression and the order in which its
-sub-expressions are themselves evaluated.
