There are no errors, just unnecessary abstractions and control flow hacks.
You try to open a file; either you can or you cannot, and both possibilities are equally likely and must be handled by normal control flow in your program. Forcing an artificial asymmetry in the treatment of both cases (as championed by the error handling people) adds ugly complexity to any language that tries to do so.
