Comment (by michel):

 Hi John,

 The use of `is_abstract<To>` in
 `boost::detail::is_convertible_impl_dispatch_base` disallows
 `To` to be an array of incomplete types. For example,
 {{{
 struct incomplete;
 bool b = is_convertible<int, incomplete[]>::value;
 }}}
 produces a compilation error, but this code is fine in C++11.

 Michel
