Backport #8025: Module#included_modules includes classes

• Status: Closed

I see two problems in the following code:

module Mixin
end

class C
  prepend Mixin
end

C.included_modules # => [Mixin, C, Kernel]

1. C should definitely not be there, since no class should ever appear in that list.

2. I wonder if Mixin should be there, since it was prepended to C, not included.

Hello,

A problem seems to remain in case of inherited Class was prepended by a Module.
See the following sample.

module M1; end

class C1
prepend M1
end

class C2 < C1
end

p C1.included_modules # => [M1, Kernel]
p C2.included_modules # => [M1, C1, Kernel]

Thanks,
