Dear Ed, Thank you for announcing this! I don't have any projects right now that need permutations, but I have in the past, and while there is some support for permutations in mainline Julia, permutations as a data type are definitely useful!
I'm wondering if you're interested in creating an official package out of this? It would require a few small changes to follow Julia conventions, but would make it easier for people to test. What do you think? Cheers! Kevin On Thursday, July 24, 2014, Ed Scheinerman <[email protected]> wrote: > Dear all, > > I've created a Permutation data type for Julia.
