I don't like this PR. The problems it can solve are very limited, and the way to solve the problem is not an excellent solution worth promoting.

After the introduction of lambda in Java 8, the cumbersomeness brought by checked exceptions became more prominent. I think we need a more general construct to solve this, rather than just adding some helper methods.
