:D You're comparing turbo pascal with Go today? You're gonna write microservices and web applications with Turbo Pascal?
In any case it doesn't change the fact that Go's compilation speed is nothing to brag about, it has been done before in many other languages, Turbo Pascal was just one example.
If you wish I can provide other examples of languages that compile as fast, on such old hardware while matching Go's compilation speed, with richer language features.
