The std::function is just as "real" as any delegate.


And the variable capture [&] is just as real as in any other 
language.


The only difference is that you have to manage the lifetimes of 
variables instead of having a GC randomly pause your app.

So if you want to _return_ an object, you have to make sure it's 
valid.

That makes it no less "real" than any other type of delegate; 
it's just forcing you to think about the lifetime of the context.

Welcome to C++ I guess?
