RE: using error x as a placeholder

[ moved to glasgow-haskell-users@haskell.org ]

The timing results were:

mkArray1: 11.42u 0.79s 0:13.47 90.6% mkArray2: 24.55u 2.31s 0:30.12 89.1%

Which is actually *slower*. Any ideas why? (These were compiled with ghc 5.02.3 -O2 -fvia-c -fall-strict)

What are the results without -fall-strict? (-fall-strict is an old experimental flag and almost certainly doesn't do anything reasonable. We've de-documented it in the HEAD). Cheers, Simon
