It's more a limitation of the current design - if the "To" template parameter is a type which can not be used as a function parameter (which is the case here)
It cannot be passed by value, but i'm quite confident that it could be passed by (const) reference.
OK, but I'm not sure if that change would break the implementation or not... will investigate.
Switching to the implementation to use the __is_convertible builtin fixes this issue BTW, but unfortunately causes other issue...
Are you talking about switching the library implementation,
Yes, I'm talking about switching the implementation - it's probably something we should do at some point, but it means a breaking change from TR1/Boost behaviour to C++0x behaviour. John.
