Ewhen is now the only case of possible recursion for minils exps. This add was motivated by equations like : (y,z) = f(x) when c This equation to be correctly normalized in minils before needed : y',z' = f(x) y = y' when c z = z' when c But this new variables where needless since the final translation of when c is the identity.
