I like that. The great virtue of ||= is that it can be explained as
repairing a non-orthogonality, thereby making the language *simpler*
to explain. But ||= is accident prone due to the falsy issue. &&= is
not as accident prone, but makes the explanation of the language more
complex.

Default parameter values are intuitive and reliable.
