That's really nice, but I think the syntax might be improved. How about adding a ::value to enable_if (and the other templates) to allow your example to look like this:

template< class... T, bool = boost::enable_if_c< sizeof...( T ) == 10>::value> test( T&&... );

template< class T, bool = boost::enable_if< boost::is_arithmetic< T> >::value> operator T() const;

etc.? Get rid of typename, *&, boost::enabler and if you like, you can write 'bool Enabled = ...' instead of 'bool = ...' to be more verbose in your code.

Hm. Why not template< class T, BOOST_ENABLE_WHEN( boost::is_xxx<T> ) > ? -Thorsten
