 Debugging stack overflows can be very difficult, because GHC gives very
 little information as to exactly what is overflowing. Showing a basic
 stack dump (on crash, or in the ghci debugger) would be enormously
 helpful.

 (Entered after spending two days trying to determine the cause of a stack
 overflow, before discovering it was a GHC bug [3677], which would have
 been apparent immediately if I could have only seen a callstack.)
