If my halt deciding computation can be performed on a Turing machine
then it necessarily meets the formal definition of a computation, right?
 
When you try to tell me that black cats are not black I know that what
you say is not true.

This would mean that my halt deciding computation cannot be performed on
a Turing machine, right?
 
Since my halt deciding computation can be translated into the RASP
computational model and performed on a RASP machine this would prove
that it can be performed by a Turing machine, right?

I can't help thinking that if you need syntax that mangled perhaps you should
revisit your design.

I wouldn't need syntax as mangled as this if I weren't working around a
deficiency in VS2019.
