702 * What happens is that instantiating a generic MethodBuilder with its own arguments should create a diferent object.
703 * This is opposite to the way non-SRE MethodInfos behave.
705 * This happens, for example, when we want to emit a recursive generic method. Given the following C# code:
707 * void Example<T> () {
711 * In Example, the method token must be encoded as: "void Example<!!0>()"
713 * The reference to the first generic argument, "!!0", must be explicit otherwise it won't be inflated
714 * properly. To get that we need to inflate the MethodBuilder with its own arguments.
716 * On the other hand, inflating a non-SRE generic method with its own arguments should
717 * return itself. For example:
719 * MethodInfo m = ... //m is a generic method definition
720 * MethodInfo res = m.MakeGenericMethod (m.GetGenericArguments ());
723 * To allow such scenarios we must allow inflation of MethodBuilder to happen in a diferent way than
724 * what happens with regular methods.
