Just weighing in with a small point, but
1.0.to_f #=>1.0

A type *like* a float responds to to_f, to give a float. For any type to act
like a float, it must quack like a float, in the sense it gives a meaningful
float when it hears to_f. #to_x messages are just messages. It is not
casting - unless you are wacky enough to write a #to_f! method. Its asking
the object to show its face as a float.

The Aussies, Kiwis, Indians and Dutch fought with unquestioned
determination and heroism. Unfortunately, they suffered from poor
(British) leadership, diversion of resources to the European theatre,
where they had been in the fight from the beginning, and the same degree
of unreadiness as U.S. forces.

However,they were unable to stop the well trained, equipped and led
Japanese forces on land, and simply had no means to stop the IJN at sea.
Australia would have been reduced and invaded (with tough Aussies
making them pay for every inch) without the presence of the USN
carriers' fleet air power. That really can't be disputed. The battles
of the Coral Sea and Midway ended Japan's plans against Australia.
However, the Aussies' brave resistance helped buy time for the allies to
organize and begin the long march to victory.
