Verbose and explicit is what made java checked exceptions the sign of the demon for some programmers. The err pattern in GO might end up the same. In the end I think the problem is that there are two separate classes of programs. The first is where crash on exception is tolerable and even a desired property (or blindly and optimistically continuing). The second is always deal with exceptions and any error no matter how rare and unlikely they are, and attempt to recover and deal with them properly. No one language and standard library can really please both sides.
