If the "real world application" is, say, only to mutltiply 10^6 `float' matrices of size 40 x 40, then FORTRAN is the best. If the application has to perform some non-trivial symbolic computations, then Haskell is better than C - even if Haskell was slower 100 times. Because in the latter case, the order of the algorithm cost matters much more, and there appear many different non-trivial algorithmic solutions. ------------------ Sergey Mechveliani [EMAIL PROTECTED]
