The current approach has several problems: - Types that are not inout types but loadable may incorrectly get marked as inout types. - When inout arguments get inlined or otherwise optimized LLDB cannot rely on the type to decide to dereference that value. - One argument may get represented by different types in the same function depending on what code is generated for it.
