[ublas] question on E::value_type for vector_expression<E>

Hi

   when we have vector_expression<E>, does E::value_type always evaluate 
to a float or double or long double? Or could it evaluate to something 
more complex like vector_reference<?> or vector_container<?>.

   I am writing functions that accept a vector_expression<E> as an 
input. I'd like to know the data type of each element in that vector and 
that is how this question has come up.

Thanks in advance!
