C++ as well as D have anonymous functions. C++: [](auto a, auto
b){ return a + b;} , D: (a, b) => a + b or (a, b){return a +
b;}. As far as I know capturing other variables requires the GC
in D. In C++ you can explicitly capture variables by copy, ref
or move. Lambda functions in D can not return references. C++17
will also make lambda functions available with constexpr.
Lambda functions can also be used at compile time in D.
Is this really true? Couldn't the closure be stored internally
somewhere like std::function<> does in C++?
I think this is actually not true, but I wrote it because of this

I run into this problem a couple of times.
