Surely you can remove the read here, and just always do the write?

Ah you'd think so, but if it's anything like the C# version, strangely that would be slower. In his last message Don explains that this is because the write dirties the cache, which is a Bad Move (tm).

Ah, it was faster in GHCi, and I couldn't test it compiled because my GHC install is a bit messed up at the moment... -- Sebastian Sylvan +44(0)7857-300802 UIN: 44640862
