map syntax Expressions.Expression.Parenthesized -> DotNet.Expr
{
    Parenthesized {
        Expression -> Expression; // error : Rule 'CSharp.Core.Expression' has no AST mapping.
    }
}

AST:

abstract ast Expr : BindableAst
{
    ...
    | Parenthesized {
        Expression : Expr;
        Type = Expression.Type;
    }
