In ghci 6.4.1, we get some useful information with the error:
{{{
Prelude> :m +Data.Array.IArray
Prelude Data.Array.IArray> (listArray (1,4) [1..4] :: Array Int Int) ! 5
*** Exception: Ix{Int}.index: Index (5) out of range ((1,4))
}}}
In ghci 6.8.3, that disappeared:
{{{
Prelude> :m +Data.Array.IArray
Prelude Data.Array.IArray> (listArray (1,4) [1..4] :: Array Int Int) ! 5
Loading package array-0.1.0.0 ... linking ... done.
*** Exception: Error in array index
}}}
ghci 6.11.20081004 is similarly unhelpful:
{{{
Prelude> :m +Data.Array.IArray
Prelude Data.Array.IArray> (listArray (1,4) [1..4] :: Array Int Int) ! 5
Loading package syb ... linking ... done.
Loading package array-0.2.0.0 ... linking ... done.
*** Exception: Error in array index
}}}
