Question

Can someone point me to examples of multiparadigm (object-functional) programming in F#?

I am specifically looking for examples which combine OO & functional programming. There's been a lot of talk about how F# is a hybrid language but I've not been able to find examples which demonstrate the example of multiparadigm programming.

Thanks

I made a small (600 lines) Tetris clone with F# that is Object Oriented using XNA. The code is old (uses #light) and isn't the prettiest code you will ever see but it's defiantly a mix of OOP and functional. It consists of ten classes. I don't think I pass any first class functions around but it's a good example of the F#'s functional power in programming the small.

• MyGame - Inherits XNA main game class and is the programs entry point.
• Board - Keeps track of pieces that are no longer moving and horizontal line completes.
• UI - The UI only has two states (playing and main menu) handled by bool stateMenu
• Tetris - Handles game state. Game over and piece collision.
• Piece - Defines the different Tetris shapes and their movement and drawing.
• Player - Handles user input.
• Shape - The base graphic object that maps to primative.
• Primative - Wraps the Vertex primitive type.

I made a rough class diagram to help. If you have any questions about it feel free to ask in the comment section.
