  `Take some more tea,' the March Hare said to Alice, very
earnestly.

  `I've had nothing yet,' Alice replied in an offended tone, `so
I can't take more.'

  `You mean you can't take LESS,' said the Hatter:  `it's very
easy to take MORE than nothing.'

  `Nobody asked YOUR opinion,' said Alice.

API changes
-----------

We make changes to Guava's public [APIs][], including adding new APIs, very
carefully. Because of this, if you're interested in seeing a new feature in
Guava, the best approach is to create an [issue][] (or comment on an existing
