Neither those. I wasn't nitpicking. Efficient threadsafe implicit sharing while fulfilling all languange requirements seems to be impossible. The only efficient and 'commonly' deployed optimization seems to be storings 'small' strings (i.e. up to 16 or 32 bytes) directly in the object, not on the heap. Andre'
