I think it would be great if named scopes had a bang (!) variation
which applies to the current scope instead of returning a new scope.
This is very useful if you need to apply scopes conditionally like
topics = Topic.approved
topics.replied! if only_show_replied?
topics.scoped! :limit => limit if limit
I would love to get some feedback on this. Would you like to see the
same thing? You can find the patch here:
