error: get Abort from 'error' instead of 'util' The home of 'Abort' is 'error' not 'util' however, a lot of code seems to be confused about that and gives all the credit to 'util' instead of the hardworking 'error'. In a spirit of equity, we break the cycle of injustice and give back to 'error' the respect it deserves. And screw that 'util' poser. For great justice.
