No problem.

That's fair, though as noted by others, all you need to do us add a 
nested type typedef which has a nested value constant, which (I think) 
can even be the metafunction class itself.  You'd still keep the value 
bool constant in the original class as well.  Example (not 100% sure 
this is correct):

template< class T >
struct metaf
{
     // Or use BOOST_STATIC_CONSTANT( ... ) ?
     static const bool value = ...;
     typedef metaf type;
};
