Hi Eric, Is it correct that the above example just generates a sequence of calls to f0, one for every child of the expression? If so, we are currently implementing that functionality like this: https://github.com/coolfluid/coolfluid3/blob/master/cf3/solver/actions/Proto/ExpressionGroup.hpp So for us this would avoid the (in this case quite simple) primitive transform.
