This is especially true with Java 8's lambda syntax and method references. Because a Java function's signature includes its checked exceptions, implementing a functional interface can require lots of verbose nested try-catches.

e.g. rather than being able to write:

  foodOnPlate.forEach(this::eat);

You end up having to write:

  foodOnPlate.forEach(food -> {
      try {
          eat(food)
      } catch (Barf e) {
          // handle?  rethrow as unchecked?
      }
  });

This library does a pretty god job handling that case:
