I guess, but less of a hybrid, if every single time I debugged Ruby I had to run GDB and constantly found myself reading C source I think it would be closer. If every time I wrote I line of Ruby I had to construct a mental model of the way MRI is going to translate the thing to C (for example because I need to know its going to wrap up my switch statements in a closure or what have you), we would be a more of a hybrid system.
Well, we have seen almost no contributions from the community wrt refactoring our js and we are a HUGE js app. In contrast we have seen massive amounts of refactoring around the Ruby side of things. Impossible for me to pin this on CS as I have no crystal ball, but it is a fact.
On a personal level I would be happy to never use CS again, I feel my hands are tied in weird ways and it encourages me to write stuff that I probably would never have written in the first place (like 4 levels of nested functions)
