class Curry<T>
{
public delegate T BoundFunc(params object[] args);
public delegate BoundFunc CurriedFunc(params object[] args);
public CurriedFunc Make(object instance, string methodName)
{
MethodInfo mi = instance.GetType().GetMethod(methodName);
return delegate(object[] pre)
{
return delegate(object[] post)
{
ArrayList al = new ArrayList();

}
}
ジェネリクスを使う意味がよくわからない。
あとこれだとcf(1)(2)(3)(4)みたいに何度も束縛できない。
いまいちだなあ。
