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: https://github.com/diffplug/durian/blob/master/test/com/diffplug/common/base/ErrorsExample.java?ts=4 https://github.com/diffplug/durian/blob/master/test/com/diff...
