Hi John,
Any chance of seeing the benchmark? You're not the only one with an
optimising compiler tucked away somewhere :-)
I have one "benchmark" where I outperform GHC by 21 times, although
saying it's artificial is a bit of an understatement...
Thanks, Neil

Here are jhc's timings for the same programs on my machine. gcc and ghc both used -O3 and jhc had its full standard optimizations turned on.
jhc: ./hs.out 5.12s user 0.07s system 96% cpu 5.380 total
gcc: ./a.out 5.58s user 0.00s system 97% cpu 5.710 total
ghc: ./try 31.11s user 0.00s system 96% cpu 32.200 total
As you can see, jhc shines at this example, actually beating gcc -O3. It isn't too surprising, this is exactly the sort of haskell code that jhc excels at.
John
