Hi, When a language is selected for a project, a practical matter is what the language provides. For example, if I need to use regex a lot, I probably want to use perl rather than other languages, because perl is the best in terms of regex and have much influence on other languages that have support on regex. If I need to do a lot of statistics, I'd better use R, because there are already a lot of statical packages implemented in R. And if there is a statistical method, it is most likely to implemented in R first. If I want to implement matrix numerical algorithm, I'd better use Fortran. After reading some wiki pages of haskell, it is not clear to what area haskell is really good for. One strong point seems to be a testbed for trying new languages. But this seems to be the case for other functional languages as well. Is there an application area in which haskell is much stronger than other different languages? -- Regards, Peng
