It should unify: (foo ?x . ?y) If it doesn't we should open up a ticket for that. On Sunday, March 4, 2012, Jonas wrote: > > > On Sunday, March 4, 2012 9:39:19 PM UTC+2, David Nolen wrote: >> >> This is just ... fantastic! :D >> > > David, quick questi

Google Summer of Code 2012 Proposal & Backup Mentors

http://dev.clojure.org/display/community/Google+Summer+of+Code+2012 A reminder that we're still looking for proposals from community members and interested students. We're also looking for backup mentors - if you'd be willing to step up this summer should something happen to a mentor please say so

Re: Google Summer of Code 2012 Application

Looks like Dan Friedman, William Byrd and the IU Googlers they know might be getting behind our application as vouchers. There's no better time to submit proposals or step up to be a mentor than now :) David On Wed, Mar 7, 2012 at 1:47 PM, David Nolen wrote: > I've made some

Re: [Clojurescript] Way to avoid function call indirection in deftypes?

The overhead is not as great as you think. In the newer crop of JS engines it's surprisingly small and I imagine that it will get smaller. I don't see this getting changed anytime soon as it allows for polymorphism as well as handling the default case if provided. If you see a better way to get th

Re: [Clojurescript] Way to avoid function call indirection in deftypes?

Nope, JavaScript has a terrible notion of truth. What if you want to add functionality to numbers? Or strings? 0 and blank strings are false-y. That said I have a branch where we inline the truth test which does a give a perf boost on many JS engines. This needs to benchmarked more thoroughly befo

Re: [Clojurescript] Way to avoid function call indirection in deftypes?

In my branch the truth test is always inlined. Support for type-hints and inference in the compiler could simplify the test when possible. On Thursday, March 8, 2012, Philip K wrote: >> Nope, JavaScript has a terrible notion of truth. What if you want to add functionality to numbers? Or strings?
