In many ways. Especially in the context of 8-bit strings, or even just the fact that strings are shared? But I'm not sure how much the accuracy of this reporting matters (if at all). 744782 1 eric 2012-10-17 16:46:43 -0700 Or the fact that if m_plainString is already isAtomic() than m_atomicString is never causing any allocation. :)
