Re: [boost] "Small buffer optimization" for boost::function?

boost::function adds to this the "manager" and "invoker" pointers, which would bring us to 20 bytes in the SBO case. But, we can collapse the manager and invoker into a single vtable pointer, so we'd get back down to 16 bytes.

FWIW, I've just committed changes that compress the manager and invoker pointers into a single vtable pointer. boost::function is now 8 bytes (on most 32-bit platforms); we can try the SBO from there. Doug
