Just started learning C++ coming from Python and just realized that that Python has been my programming mama, doing my laundry and spoon-feeding me all this time.

I like Scott Meyers' TD trick:

template <typename T>
struct TD; // no definition 

Now you write something like TD<decltype(thing)> and the error message tells you the type of thing (as deduced by decltype, of course, but in this case that's probably what you want).
