背景:

• ruby认为即使我指定了完整的命名空间,我也引用了顶级常量
• 如何在ruby中引用子模块的"完整路径"？

这是问题所在,简化为最小的例子:

# bar.rb
class Bar
end

# foo/bar.rb
module Foo::Bar
end

# foo.rb
class Foo
  include Foo::Bar
end

# runner.rb
require 'bar'
require 'foo'

? ruby runner.rb
./foo.rb:2: warning: toplevel constant Bar referenced by Foo::Bar
./foo.rb:2:in `include': wrong argument type Class (expected Module) (TypeError)
    from ./foo.rb:2
    from runner.rb:2:in `require'
    from runner.rb:2
