the new CSE-acceptance is a nice idea, but imho it's not intelligent enough yet.
basially, it should be "smart completition backwards". CSE acceptance should offer methods that match the given return values and variables. currently, it simply wraps the rest of the line between (), which is what i'd expect from eclipse, not from idea. idea should do some internal "ctrl+w"s to see what actually would make sense (or give valid code) to wrap between () (for example, if it is a method taking more than one parameter) and let the user choose between different possibilities if there is more than one.
