While the case for strings is certainly quite domain specific (but I've seen this specifically about a dozen times), there is something in the underlying set of requirements that seems to be general enough. Memory pool allocation comes to head, but that only handles fixed-sized objects, so, I'm more than interested in the underlying mechanisms for such a library because it seems that there might be a general utility behind it. So, @Steve, would you like to disclose and discuss the underlying details here, keeping an eye on abstracting the type of object being managed? -- Fernando Cacciola SciSoft Consulting, Founder http://www.scisoft-consulting.com -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
