Personally I am not one of those that constantly screams "eval is evil".
Eval has use cases.

In this scenario though, const_get is a lot better than eval IMO.
It does exactly what you need here, no need to add more complexity
by eval-ing statements - evals tend to be less readable normally too. :)

By the way, i think a hierarchy like "A::B::C::D::E" looks rather 
contrived.
In practice I even find it hard to see "A::B::C" hierarchy used a lot, 
at least
at the code parts I had a look at. Normally I see only one Module, and
inside it a few other classes (sometimes modules, and then a class 
inside too,
but that is quite rare)
