C#-like properties in native C++?

Question

In C# / .NET you can do something like this:

someThing.text = \"blah\";
String blah = someThing.text;

However, the above code does not actu

By using std::function you can get pretty close. Featurewise everything is here.

First create the templated Property class:

#include 

template
class Property
{
    std::function _get;
    std::function _set;
public:
    Property(
        std::function get,
        std::function set)
        : _get(get),
          _set(set)
    { }

    Property(
        std::function get)
        : _get(get),
          _set([](const unsigned int&){})
    { }

    operator T () const { return _get(); }
    void operator = (const T& t) { _set(t); }
};

Use the Property in a class by creating a get and a set method similar to what you would in do C#:

class Test
{
private:
    std::string  _label;

public:
    Property Label = Property
    (
        [this]()->std::string
        {
            return this->_label;
        },
        [this](const std::string& value)
        {
            this->_label = value;
        }
    );
    Property LabelSize = Property
    (
        [this]()->unsigned int
        {
            return this->_label.size();
        }
    );
};

Testing this code:

Test test;
test.Label = "std functional";

std::cout << "label      = " << std::string(test.Label) << std::endl
          << "label size = " << int(test.LabelSize) << std::endl;

will output

label      = std functional
label size = 14

I think this is as syntactic-sugar-coated as you can get it in c++ :)
