9100	has_*_operator.hpp generates C6334 using VC++	ianjirka@…	John Maddock	"Warning	2	warning C6334: sizeof operator applied to an expression with an operator might yield unexpected results:  Parentheses can be used to disambiguate certain usages.	c:\users\ian\dev\tensor\main\code\external\boost\latest\boost\type_traits\detail\has_binary_operator.hpp

This can be fixed by adding an extra set of parentheses around returns_void( ... ).  For example:
sizeof((returns_void(...))

For example:  has_binary_operator.hpp:95
Was:
    BOOST_STATIC_CONSTANT( bool, value = (sizeof(::boost::type_traits::yes_type) == sizeof( returns_void( (make<Lhs>() BOOST_TT_TRAIT_OP make<Rhs>(), returns_void_t()) ))) );
With fix:
    BOOST_STATIC_CONSTANT( bool, value = (sizeof(::boost::type_traits::yes_type) == sizeof((returns_void( (make<Lhs>() BOOST_TT_TRAIT_OP make<Rhs>(), returns_void_t()) )))) );

I was able to fix has_binary_operator.hpp and has_prefix_operator.hpp this way.  I'm sure other metafunctions are affected as well."	Bugs	closed	To Be Determined	type_traits	Boost 1.54.0	Problem	fixed
