No, vice versa. I *could* support any magic slot and put
it into the extended type object with a Python name.
And even better, this version could have full type
checking, as my other methods have as well! This could
go far beyond what we have now. My system is explicit
at types: You repeat the whole function argument list
in the newly grown slot. This is as type safe as can be.
