The reasons to use macros instead of RAII is convenience and performance.
Can you elaborate please. I'm slowly coming to the conclusion that any catch that can be replaced by RAII should be. Including the one in shared_count. ;-)
I think I can contribute here. Earlier versions of indexed_set did extensively use scopeguards in place of try-catch blocks. When doing the performance measures, I discovered that scopeguards were introducing a non-negligible penalty --for instance, a single-indexed indexed_set was 20% slower than its equivalent std container with scopeguards, and just 10% slower with try-catch blocks (rough figures.)
