I don't know if anyone else agrees with me, but I think the idea of having
the wrapper be configurable with a policy to handle the errors is highly
attractive.
The alternative would be to have a bool checkForErrors and check if before
checking and handling errors. This would imply run-time overhead, while
using the policies would not.

What do you think ?
