3:53 thiagofm: well hold on
betawaffle
3:53 i can give you some pointers
3:53 don't copy the uglyness
3:54 erlang optimizing certain binary matching situations, and i exploit those to try to lose as little time as possible
3:55 you need the first argument in each matching function to be the binary you are matching

hi guys. I have a factory that returns a resource like this:   

return $resource('/api/:key.json', {key: '@key'}, {
  'delete': { method: 'DELETE' }
});

when I do:

    Key.delete(pair, function (response) {
      console.log(response);
