TicTacToe (No CPU Tho)

[Capital-EX]

I made a small game of tic tac toe using Cyber:
https://codeberg.org/CapitalEx/scratchpad/src/branch/main/tic-tac-toe.cy

It's already a nice language to work with; however, I did hit a few road-bumps.

Currently, enums and symbols can't be used as types. So, I can't add types to a function like:

func stateToPlayer(state):
    match state:
        #cellX: return #playerX
        #cellO: return #playerO

List can't have their values typed. So Just use untyped List. This lead to me trigger a hard to figure out error #68:

func makeGrid() List:
    var grid List = []
    for 0..3:
        var row List = []
        for 0..3:
            row.append(#cellEmpty)
        
        grid.append(row)

    return grid

No optionals or union types (a la TypeScript, Flow, Crystal, Scala, etc.) means you have to fallback on any when returning an optional value:

func checkForWinner(self):
        for checks each line:
            var winner = none

            for line each pair:
                var row int = pair[0]
                var col int = pair[1]

                if not winner:
                    winner = self.grid[row][col]

                else winner != self.grid[row][col]:
                    winner = none
                    break
            
            if winner and winner != #cellEmpty:
                return winner
        
        return none

As I said before, the language is already quite nice to use. It has the same "light" feel that I enjoy with Lua, and I'm looking forward to seeing where it goes!
