I know that, I was expecting it to work with multiple ranges if the
functor takes multiple arguments.

A *lazy* range of associative arrays.

Same answer as above.

My custom range implementation shows exactly what I was trying to use
map for. It only seems natural to me to have this ability, but maybe
map!() can't be customized for this use. Anyway I'm satisfied with my
approach unless you can make map!() do the same thing with some zip
tricks or something.
