Subject: [ruby-talk:24200] Re: "yield called out of block"

Because yield can be used for all sorts of useful things, and returning 10,000
values from a function requires having 10,000 * sizeof(item) bytes allocated,
whereas iterating through them with yield would only require one instance of
said item in memory during each iteration.

OTOH, I have no idea how values works in CL, so I could be putting my foot in my
mouth.

Besides, you CAN return multiple values in ruby, really. There's a built-in
array type.
