for key in self.my_dict.iterkeys():...

I currently have some python code I'd like to port to C++ as it's currently slower than I'd like it to be. Problem is that I'm using a dictionary in it where the key is a tuple consisting of an object and a string (e.g. (obj, "word")). How on earth do I write something similar in C++? Maybe my algorithm is horrendous and there is some wa...

reduce(
lambda x,y: dict(x.items() + { y.id : y}.items()),
list,
{}
)
Suggest better way to do it.

Logically first snippet should be faster o...
