> it's simply not possible to write a wrapper function that accepts a function and calls it, and throws the same set of checked exceptions that the inner function does It is possible, and straightforward, to do that if the set of checked exceptions is of a statically known size, and the wrapper function can propagate the exceptions rather than catch and rethrow them. In my experience, that is a very common situation (although not universal). If you want to catch and rethrow, that can also be done, but it requires an evil hack, and the wrapper will need to take a reified type for the exception.
