Yeah I mixed things up a bit there as well as slightly mis-
remembering. if you do things as rails expects, and rely entirely on
the const_missing hooks then either way works. but if you deviate from
that then things are different.

For example if z.rb is

module X
module Y
module Z
end
end
end

and you do require_dependency 'x/y/z' then x/y.rb won't be loaded

but if you do

module X::Y::Z
end

then it will.

I guess the point I was trying to make was that if ruby ends up
reading z.rb then using module X::Y::Z guarantees that x.rb and x/y.rb
will be read, but the other form doesn't, although the usual scenarios
would mean that x.rb and x/y.rb would have been read earlier on
anyway.
