This is gonna haunt me.

Digging through some old code of mine (circa 2009) I found this bit:

  #elif _MSC_VER >= 1310
  #define typeof(type)    __typeof(type)

So somehow I had the impression Visual Studio .NET 2003 (7.1)[1] added __typeof. I'm still holding out hope someone will come to my rescue and reply that once upon a time MSVC had __typeof, but removed it. But for now it seems past me is gaslighting present me.

[1] See https://learn.microsoft.com/en-us/cpp/overview/compiler-vers... for mapping between Visual Studio versions and _MSC_VER.

EDIT: Ah ha! It seems Microsoft did support __typeof, but perhaps only for "managed" C++ (aka C++ .NET)?

> One thing to watch out for when using the __typeof operator in managed C++ is that __typeof(wchar_t) can return different values depending on the compilation options.
