Re: [boost] [type traits] possible bug in boost::is_convertible for types with private copy constructors

At least one thing is clear: is_convertible shouldn't ever cause a compile-time error. If one of the possible implementations always avoids a compile-time error, I vote for that one.

I believe the only time you can get a compile-time error out of is_convertible is if you use it with types which fail to meet these requirements:

From and To shall be complete types, arrays of unknown bound, or (possibly cv-qualified) void types.
