[boost] [variant] Constructible/assignable from anything

Boost variant has a constructor and an assignment operator that would 
take just anything. If it cannot be converted to any of its bounded 
types, it will result in an error within variant's internals. This, 
mixed with conversion operators, interferes with overload resolution 
(code that reproduces the issue attached). Would SFINAE'ing out the 
non-candidate constructors (and assignments) fix this?
