With the message array bounds error, would it be possible to print out the actual wrong numbers. ie

Error: ArrayBoundsError file.d(403)
range : 1..10 != 2..19

or for indexing errors
Error: ArrayBoundsError file.d(403)
index 5 is not in the range 0..10

There's a strong possibility that this information will need to be printed out anyway by the programmer.
