Description

Thank you for developing the really nice library!
It would be great to add value_type nested-type to EigenBase

template&lt;typename Derived&gt; struct EigenBase  
{  
  typedef typename internal::traits&lt;Derived&gt;::Scalar value_type;  
  // ...  
}

since this improves the interoperability of Eigen in generic programming.
(For example, vectors/matrices in Boost.uBLAS have value_type nested-type.)
