Comment (by Fedor Trushkin <ted-xp@â¦>):
Could you explain, please, why zero arguments case is handled specially? I
modified it to use the same ideas an in funwrap and it seems acting
perfectly without any compiler errors. That's how it looks like after
preprocessing:
{{{
template<typename Fun>
struct funwrap0_swap
: Fun
{
funwrap0_swap();
using Fun::swap;
boost_intrusive_has_member_function_callable_with::private_type
swap() const;
};
template<typename Fun>
struct has_member_function_callable_with_swap_impl
<Fun, true
, void
>
{
typedef funwrap0_swap<Fun>
FunWrap;
static bool const value =
(sizeof(boost_intrusive_has_member_function_callable_with::no_type) ==
sizeof(boost_intrusive_has_member_function_callable_with::is_private_type
( (boost::move_detail::declval<FunWrap>().
swap(), 0
)
)
)
);
};
}}}
For me the only worrying thing is {{{using std::swap}}} statement, as I
don't get how exactly should this be regarded by compiler if no swap is
available in {{{Fun}}} base class.
