Sure, but almost all of the uses of Optional.get() will be in the future. This rather reminds me of the early UNIX bug report about make syntax. The bug was that make(1) treated tab characters and spaces differently. This bug could have been fixed but there were about 20 users of make already, and they would have had to change their makefiles. And probably everyone reading this mail has suffered because of that bug. Andrew.
