示例1: ApplyDefMacro
public object ApplyDefMacro(IList<object> arguments, Environment environment)
{
if (arguments.Count != 3)
{
throw new ArgumentException("Wrong number of arguments given to defmacro! Expected: " + 3);
}
var symbol = arguments.ElementAt(0) as SymbolNode;
if (symbol == null)
{
throw new ArgumentException("First argument to defmacro not a symbol!");

if (parameterList == null)
{
throw new ArgumentException("Second argument to defmacro not a parameterlist!");
