import std.stdio;

void printMenu(string[] items, int firstNumber) {
    foreach (i, item; items) {
        writeln(' ', i + firstNumber, ' ', item);
    }
}

void main() {
    string[] items =
        [ "Black", "Red", "Green", "Blue", "White" ];
    printMenu(items, 1);
}

Here are some ideas:
- Write a function named drawHorizontalLine() to draw horizontal lines.
- Write a function named drawSquare() to draw squares. This function could take advantage of drawVerticalLine() and drawHorizontalLine() when drawing the square.
- Improve the functions to also take the character that is used when "drawing". This would allow drawing each shape with a different character:
```
void putDot(Canvas canvas, int line, int column, dchar dot) {
    canvas[line][column] = dot;
}
```
