You are right. But it doesn't make returning by value better, because a) it guaranteed overhead b) it is enough to forget to define explicit assignment operator in any descendant of AutoStorage and compiler-generated bitwise one will replace original pool with pool of the temporary object. As the result, it is better to implement assignment operator on target size that conversion methods on source side. I.e. instead of writing "a = b.toString();", write just "a = b;". -- WBR, SD. ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
