Rename .address property returned by resolve hook to .url; rename first argument to fetch hook from address to resolved.
Support resolveResult.other.
Add default arguments to evalAsync, improve its doc comment.
Ban module declarations for modules that already exist or are loading.
Rename done/fail to callback/errback everywhere. Remove issue about whether loader.load() captures the result of evaluating the script and passes it to the success callback, like evalAsync: it does, per meeting 2013 April 26.
load() takes an options argument which can contain a referer url. Remove resolved issues.
Throw from fetch callbacks if they are called more than once.
