Re: [Haskell-cafe] Troubles understanding Parsec Error Handling

in mind that 'try p' pretends that it hasn't consumed input when 'p' fails. I don't think you need to use 'try' in your 'anyOf' function, but you'll have to change it to handle seeing the end of input if the one-character look-ahead fails. Kevin -- Kevin Charter kevin.char...@acm.org

Re: [Haskell-cafe] Troubles understanding Parsec Error Handling

. And Roman, thanks for the light-speed patch! I was about to say I had an example that showed the problem might actually have to do with 'lookAhead' rather than 'try', and then I saw your message. Kevin -- Kevin Charter kevin.char...@acm.org ___ Haskell-Cafe

Re: [Haskell-cafe] Can Haskell outperform C++?

. Not so much that it's typically two or three or ten times slower than language X, but that it's easy to have a bad experience *early on*, one that seems inconsistent with the language shoot-out and other performance comparisons. Kevin -- Kevin Charter kevin.char...@acm.org

Re: [Haskell-cafe] Can Haskell outperform C++?

acceptable performance with GHC when I've made good use of the tools for finding space and time leaks. And it hasn't been hard, just something I had to learn to do. Gregg Kevin -- Kevin Charter kevin.char...@acm.org ___ Haskell-Cafe mailing list Haskell

Re: [Haskell-cafe] I am having trouble with the type declaration for creating an identity matrix.

correct. Kevin -- Kevin Charter kevin.char...@acm.org ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Re: [Haskell-cafe] How do you test a parser?

need 't' to strip them out. Kevin -- Kevin Charter kevin.char...@acm.org ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
