Thanks to Eric and Joel, it now works. Just for info, the solution:

 

// grammar forbidding address of for terminals

struct state_grammar : proto::not_<proto::address_of<proto::_> >

{};

// Forward-declare an expression wrapper

template<typename Expr>

struct make_state;

struct sm_domain

: proto::domain< proto::generator<make_state>, state_grammar >

{};

template<typename Expr>

struct make_state

: proto::extends<Expr, make_state<Expr>, sm_domain>

{

typedef

proto::extends<Expr, make_state<Expr>, sm_domain>

base_type;

// Needs a constructor

make_state(Expr const &e = Expr())

: base_type(e)

{}

// Unhide Proto's overloaded assignment operator

using base_type::operator=;

};

 

Then, to define a terminal:

struct s1: make_state<proto::terminal<state_tag>::type>{};

 

Thanks a lot!

 

Regards,

 

Christophe
