> If they truly wanted to have platform-dependent int, then why 64-bit int on 64-bit platforms wasn't introduced from day 0? It's a valid question, because it would avoid this big (implementation) change at all. Because we have finite time, and it was easier to implement at the time. This property has been in the language spec since day 1. It should not come as a surprise to anyone. How much of my hundreds of thousands of lines of Go code have I needed to change because of this implementation change? None.
