> [@MegaIng](#): > > IMO I think using normal python functions to do these kinds of type transformations should be reconsidered as I think that’s definitely the best option. Yes, it is quite complex to implement, although I am unsure why it would be significantly more complex than the current proposal. And it would, with a bit of care, make the code readable in a way that the current proposal never will be. This would require typechekers to implement Python runtime in them too. And it’s highly non-trivial. This shifts the complexity and makes it someone else’s problem, which in reality will mean that we’re just not solving this problem at all and stalling. --- _[View the full topic](https://discuss.python.org/t/pep-827-type-manipulation/106353)._
