  If x is outside the integer range, the function returns a long instead.
  
  If x is not a number or if base is given, then x must be a string or
  Unicode object representing an integer literal in the given base. The
  literal can be preceded by '+' or '-' and be surrounded by whitespace.
  The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to
  interpret the base from the string as an integer literal.
