Guice 1.0 vs 2.0

The Guice 2.0 contains lots of neat improvements. It removes lots of unnecessary boilerplate and allows to write more compact Guice modules. Here is an example of how a confusing binding can be refactored into a simple provider method.

Example using Guice 1.0:
@Override
protected void configure() {
bind(new TypeLiteral<List<string>>(){})
  .annotatedWith(TagsToProcess.class)
  .toProvider(TagsProvider.class);
}

The same example using Guice 2.0:
@Provides @TagsToProcess
public List<string> provideTags(@Named("tags") String tags) {
  return ImmutableList.of(StringUtil.splitAndTrim(tags, ","));
}

Yeah, I love the way annotations work with provider methods.
