Not compile-time checked repetitive error handling (if null != err), duality of panic and error codes, specially blessed constructs (maps, slices, etc being "generic"), lack of expressivity, specially typed map libs, interface{} type safety escape hatch, etc...

If err != nil everywhere is definitely a code smell and poor language design.
