Hi everyone, I'm trying to make a search bar with buffwr. If we 
go through something simple like this:

```d
module searchbar;

     string name;

     }

     void draw() {
         // Draw search bar background
         DrawRectangleRec(bounds, backgroundColor);
         DrawRectangleLinesEx(bounds, 2, DARKGRAY);

         // Draw input text
         Vector2 textPos = Vector2(bounds.x + 10, bounds.y +

     auto searchBar = new SearchBar(searchBarBounds, font);

     // Main game loop

         searchBar.handleInput();

         // Draw
         BeginDrawing();
         ClearBackground(RAYWHITE);

Would you mind if I could use your suggestions?

Thanks...
