Subject: Getting Module from Symbol

I want to use methods in different modules depending on commandline switches. So I thought i'd use

module Module1
  module SubModule1
    def foo() end
  end

  module SubModule2
    def foo() end
  end
end

module Module2
  module SubModule1
    def foo() end
  end

  module SubModule2
    def foo() end
  end
end

m1 = Module1
m2 = SubModule1

m1::m2::foo()

to call the correct foo depending on m1 and m2.

This does not work, because when assigning SubModule1 to m2 it is not defined.

Logical conclusion, I want to name the module, not take the module when assigning the variable => I have to use a symbol. But then I do not want to call m2 on the Symbol :Module1, so somehow I have to go from symbol to module.

Is eval the only way to do this, or is there something more elegant?

Thanks,

Brian
