Python 3.12+ `type` keyword not supported in command types

[Paillat-dev]

Summary

type cannot be used to type command types when it should.
Using type is the preferred way to create type aliases in python 3.12+ instead of assigning to a variable directly.

bot = bridge.Bot(intents=discord.Intents.all(), command_prefix="!")


class MyCustomContext(
    bridge.BridgeExtContext
): ...  # I want to do this for whatever reason, doing this *is* supported


type Context = MyCustomContext | bridge.BridgeApplicationContext

reveal_type(Context)

class MyCog(discord.Cog):

    @bridge.bridge_command()
    async def ping(self, ctx: Context, ephemeral: bool = False):
        await ctx.respond(f"Pong! {round(bot.latency * 1000)}ms", ephemeral=ephemeral)

bot.add_cog(MyCog())
