He's saying use the resources the community have already provided, to write it in a lower-level style, following much the same pattern as Don did. > So all that bravado about Haskell enabling higher-level optimisations to > produce a result faster than C is actually complete nonesense? Nope. If you just code up a simple algorithm in C and in Haskell, it is pretty unlikely the Haskell one will go as fast as the C one. But Haskell (in particular GHC) does have powerful low-level features that means you can probably draw with C. One day, I hope that high-level Haskell will outperform C all the time. It's already true with some of the ByteString stuff, but hopefully one day it will be a normal result. It's pretty much the goal of this optimiser: http://www-users.cs.york.ac.uk/~ndm/supero/ Thanks Neil _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
