After adding a constructor

template< typename Q = T, class = typename boost::enable_if< boost::is_complex<Q>, typename Q::value_type  > >
MyType( const MyType < typename Q::value_type>& a ) {};

your mentioned assignment actually compiles.

Well, that would be in contradiction to < https://eigen.tuxfamily.org/dox/structEigen_1_1NumTraits.html > :
" A typedef Real, giving the "real part" type of T. If T is already real, then Real is just a typedef to T. If T is std::complex<U> then Real is a typedef to U. "

O.k., I'll try harder.
