Property value by index shortcuts

[iwbnwif]

The shortcut UserObject::get(const std::string & property) is provided as a shortcut for object.getClass().property(name).get(object).

Would it be possible to provide an equivalent for indexed access to properties, i.e. UserObject::get(const size_t index)?

Justification: this helps when iterating over all properties in a class instance.

Probably it would be good to provide the set equivalent for completeness.

Another related enhancement might be to expose the property lists, at least sorted by position. This will allow the use of range-based-for to iterate through the properties (and possibly functions if there is a use case for that).

For example:

int i = 0; for (const ponder::Property& prop : metaclass.propertyList())
{
        std::cout << "Field " << i++ << " is: " << prop.name() << std::endl;

        // Check for width and hidden tags.
        if (prop.hasTag("width"))
            std::cout << "Field " << prop.name() << " has width: " << prop.tag("width") << std::endl;
}
