ctx.command object guaranteed to be identical to attributes of the cog class?

[ioistired]

class Foo(commands.Cog):
    cmds = set()
    def deco(cmd, cmds=cmds):
        cmds.add(cmd)
        return cmd

    def cog_check(self, ctx):
        return ctx.command in self.cmds

    @deco
    @commands.command()
    async def allowed(self, ctx):
        await ctx.send('allowed')

    @commands.command()
    async def denied(self, ctx):
        await ctx.send('illegal')

neither of these commands run. why is that?

For now I will use Command.qualified_name instead since that is globally-unique. Not sure if that's the correct solution, though.

Commands in cogs undergo copy operations to allow multiple cog instances to have separate command instances.

Comparison between instances is generally not allowed (evident by the fact there's no __eq__ or even __hash__) -- using Command.qualified_name is the proper solution here.
