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