Fixed. Nice !
You need to use has_member<void(), const _self> for const member functions.
Ok, I understand now. I didn't realize that has_member<void()> was actually a shortcut to has_member<void(), _self>. Thanks. 2012/11/13 Steven Watanabe <watanabesj@gmail.com>

I'm playing with the boost type erasure library (from the sandbox) and hit some issues.
<snip> In the previous code, if add a const here :
for(const any_free_t& af : v) { free(af); }
then instead of calling the int overload of the free function and the template overload with a double type, the templated free function is called both time but, unfortunately the type of T is always the same as the any.
Fixed.
Another point, if I add a const here : for(const any_member_t& am : v2) { am .member(); } then I get a compile error. (with visual 2012 and gcc 4.7)

I'm a bit puzzled by this behavior. Are any<> types never supposed to be taken by const ref ? How can we iterate over anys while preserving constness ?
