Hi Bulat, I think that is exactly the point. At least one ruby-to-c translator exists (rb2c) now, but no matter how intelligent it is, it cannot match the programmer's intelligence (especially in a dynamic typing environment like Ruby). Therefore, as we have discussed all along, if we just can have some "hints" on the type of the variables, I think any ruby-to-c translator can further be optimized to eventually approach the speed of C.
