pub struct ExprIf {
    pub attrs: Vec<Attribute>,
    pub if_token: If,
    pub cond: Box<Expr>,
    pub then_branch: Block,
    pub else_branch: Option<(Else, Box<Expr>)>,
}

An if expression with an optional else block: if expr { ... } else { ... }.

This type is available only if Syn is built with the "full" feature.
