Complex SFINAE expressions appear to be broken on the latest release of MSVC 2017.
MSVC++ 14.15 (Visual Studio 2017 version 15.8):
The parent change compiles fine.
MSVC++ 14.16 (Visual Studio 2017 version 15.9):
`error C2039: 'type': is not a member of 'std'` for some CToReactorPtr specializations that use `std::enable_if`.
Replacing these `typename std::enable_if<T>::type` with `enable_if_t<T>` works around the issue (while also making the template expressions easier to read).
I was unable to find an existing MSVC bug report for this problem, and so I will create one.
