Really, that's not very ambitious. Haskell should be setting its sights higher. :-) When I first started reading about Haskell I misunderstood what currying was all about. I thought that if you provided one argument to a two argument function, say, then it'd do partial evaluation. Very I soon I was sorely let down as I discovered that it simply made a closure that waits for the second argument to arrive so the reduction can be carried out. But every day, while coding at work (in C++), I see situations where true partial evaluation would give a big performance payoff, and yet there are so few languages that natively support it. Of course it would require part of the compiler to be present in the runtime. But by generating code in inner loops specialised to the data at hand it could easily outperform C code in a wide variety of real world code. I know there has been some research in this area, and some commercial C++ products for partial evaluation have appeared, so I'd love to see it in an easy to use Haskell form one day. Just dreaming, I know... -- Dan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
