我喜歡它的這一特色：LambdaExpression.Compile

Expression> expr = a => a + 3;
Console.WriteLine(expr); // prints "a => Add(a, 3)"
Func func = expr.Compile(); // LCG's an MSIL method from the expr
Console.WriteLine(func(4)); // prints "7"
這些程式碼等同於
(define expr '(lambda (a) (+ a 3)))
(display expr)
(define func (eval expr (scheme-report-environment 5)))
(display (func 4))
