(Btw, I blame gmail for the mangled title ;-) -- it's been doing some weird stuff recently on Safari for me; but only in the subject line. I think there were backspace characters in an edit that weren't applied.) The permuted indices are interesting. It means really committing to the style/namin

hi, I am trying to run and understand a lifting program from [1]. The program lifts points to moving points that vary their position over time. I made some effort to run the progrm but I do not know how to overide the +,-,*,sqr, and sqrt from the Num class. Below is my current attempt. I do not wi

Re: [Haskell-cafe] Haddock: patch to generate single-index page in addition to perl-letter indexes indices.

For packages with many items in the index, these pages can get a bit huge. How about a permuted index like ? E.g., for your use case, you would go to E and then the row with all the "End" entries, which would contain all the nam
