Topics will include type-level naturals and their reification vi a singleton types\, lifted data types\, kind polymorphism\, and fiddly G HC details that make all these things slightly less awesome than they sh ould be. Also included will be an object lesson in the dangers of naming and releasing too early. \;\n \;\nAlso\, we'll have Lyle Kopnicky talking on "\;Just-in-Time Compilation in Haskell"\;. \;\n&# 13\;\nSee you there! \;\n \;\nABOUT THE GROUP: Join programmers\, researchers and enthusiasts to discuss functional programming. pdxfunc i s a study/user group exploring the world of functional programming based in Portland\, Oregon. The group welcomes programmers interested in all functional languages\, including Haskell\, OCaml\, Erlang\, Scala and ot hers\, as well as using functional techniques in non-functional language s. The group meets regularly and provides presentations\, demos and disc ussions applicable to all skill levels\, from newbies and experts. The m eetings are usually on the second Monday of the month. \;\n\n\nTags: functional programming\, pdxfunc\, haskell\, epdx:group=11\n\nImported f rom: http://calagator.org/events/1250464612 URL:http://pdxfunc.org/ SUMMARY:pdxfunc: Portland Functional Programming Study Group LOCATION:Janrain Headquarters: 519 SW 3rd Ave. Suite 200\, Portland OR 97 204 US SEQUENCE:2 END:VEVENT END:VCALENDAR
