792 * The reason for this hack is to fix the behavior of inflating generic methods that come from a MethodBuilder.
793 * What happens is that instantiating a generic MethodBuilder with its own arguments should create a diferent object.
794 * This is opposite to the way non-SRE MethodInfos behave.
796 * This happens, for example, when we want to emit a recursive generic method. Given the following C# code:
798 * void Example<T> () {
802 * In Example, the method token must be encoded as: "void Example<!!0>()"
804 * The reference to the first generic argument, "!!0", must be explicit otherwise it won't be inflated
805 * properly. To get that we need to inflate the MethodBuilder with its own arguments.
807 * On the other hand, inflating a non-SRE generic method with its own arguments should
808 * return itself. For example:
810 * MethodInfo m = ... //m is a generic method definition
811 * MethodInfo res = m.MakeGenericMethod (m.GetGenericArguments ());
814 * To allow such scenarios we must allow inflation of MethodBuilder to happen in a diferent way than
815 * what happens with regular methods.
817 * There is one last touch to this madness, once a TypeBuilder is finished, IOW CreateType() is called,
818 * everything should behave like a regular type or method.
