I'm confused... above it seems you're asking for something like  
ParseTree for C/++. Below it seems you're asking for a sexp to C  
translator. Or... you want it bidirectional???

Any C/++ parser could be adapted to generate ruby objects that look  
like sexps. But conceptually there is a lot of disparity between C, C+ 
+, and ruby. I doubt you'll ever manage a clean bidirectional mapping  
between the two except for the most hamstrung subset between the three.

Curious tho: why?
