Sugar to wrap C++ classes

[sanko]

With Itanium mangling somewhat functional, defining and calling this methods should be handled internally.

[sanko]

typedef 'MyClass' => Class[
    [ speed => 'set_speed' ] => Method [ [Int] => Void ],
    speed                    => Method [ []    => Int ],
    private                  => [ fuel => Float ],
    speed                    => Int,
    driver                   => Str
];

Something like this? Usage would be something like...

my $car = MyClass->new( speed => 0, driver => 'Mike' );
$car->set_speed(100);
print $car->speed;

• So a method new( ... ) would take values and return a blessed pointer
• A private value fuel would take up space in the pointer but not exposed somehow
• Methods would automatically be made with THIS calling conventions and can be renamed ([ speed => 'set_speed' ] => ...) to avoid collisions
• Should multiple methods with the same name be wrapped in a code ref that called the correct one based on the type of values passed? I'd need a way to test parameter types beyond advisory...

Edit: In the above examples, MyClass::speed() would be _ZN7MyClass5speedEv and MyClass::set_speed($) would be _ZN7MyClass5speedEi in Itanium.

As of this comment, C++ class support includes:

• defined with CPPStruct[ ... ] (borrowing from Raku)
• constructors are simply wrapped with affix/wrap with names such as MyClass::MyClass or MyClass::new which attach to the the proper endpoint through mangling and proper handling of this pointer internally
• destructors are MyClass::DESTROY and handled internally
• no direct access to struct members (public or private)

I haven't wrapped a full C++ yet to test how unwieldy that is.
