I previously posted about RM's Code Completion and how it could be improved.
In particular, I was wondering that in case of no inferred type it should suggest methods from all classes of the codebase.
This is the very same behaviour that eCompletion, oCompletion (Smalltalk) and NetBeans (Ruby) exibit.
My team has prepared a RubyMine script that, after some tests, help us to (partially) recover that behavior:
we have uploaded the script.
Any suggestions are welcome!
