  On Ruby: Diamondback Ruby Interview

  Diamondback Ruby uses a combination of static and dynamic checks to ensure that Ruby programs are well typed. Programs that can be checked purely statically (which we hope will be most of the time) will have no overhead at all since the programs can be safely run by a traditional Ruby interpreter unchanged. However, if the program does require a runtime check, then individual objects or methods may be instrumented to ensure they don't violate their types. When dynamically checking objects, we instrument the eigenclass of the individual object so that only methods calls to that object must be checked (not every object of the same class).
