It's quite true, in fact. Look at Java's generics. Pre-Java 5, everybody was asking for generics. They got implemented. Now everybody complains they suck because they are a hack, they are slow, not that type-safe, made the language more complex, are not as powerful as C++/Ada/Haskell, etc. Nobody wants to go back to Java 4 (in which situation was worse than Go, tbh), but everybody (OK, most people) keeps complaining. I'd myself be very happy with a hint of generics in Go, though. Something at the package level, that would be instantiated at "import" time (since the import keyword is supposed to hold some magic in itself) would have my preference.
