Subject: Re: [boost] Compile time reflection for IPC using

    But I see many attempts to resolve this problem in boost::fusion e.g.
But it approch can't resolve problem different scope for fields
Like FIELDS((int) _1, (char) _2) my_struct; but not struct my_struct {
FILD(int, _1); METH(int, call_1, (int, char)); ... METH(... call_N ...) };
Therefore I think this question is actual now in context boost.
Because in approcah I sent we can collect any meta information compile
time. And I canm say it is not only compile time reflection This is very
comfortable approaches to designe.


struct rule_on_1_case
    struct roles { struct on_begin_1_case; struct on_end_2_case; };


struct rule_on_2_case
    struct roles { struct on_begin_2_case; struct on_end_1_case; };


.... N rules, or anythink in different scope

After which we can collect all types

typedef typename
   hl::manual_extrcat<rules>::type rules_typelist;
// boost::v_item<rule_on_1_case, boost::v_item<rule_on_2_case,
boost::mpl::na, 0>, 0>

And do somethink .
Compile time reflection it is only one case when this approcah can be used
