(1) Doesn't compile. Error: variable m_valueImpl cannot be read
at compile time
To use alias this for composition, it would be nice if the
compile-time evaluable members of the aliased object would remain
compile-time evaluable even when used through an alias. Is the
current behavior defined by the language or is it due to the
compiler (DMD) implementation?
