They are included in TC++PL at least. But so is everything else in C++ :) They are probably obscure because they are only really useful for logging or remapping exceptions (unless a new exception is thrown the original one will be re-thrown at the end of the catch-block) in constructors and destructors. They can be used in normal functions as well, but offers nothing beyond what normal try-blocks do there.
