...one of the most highly
regarded and expertly designed C++ library projects in the
world. — Herb Sutter and Andrei
// In header: <boost/yap/user_macros.hpp> BOOST_YAP_USER_BINARY_OPERATOR(op_name, expr_template, result_expr_template)
Defines operator overloads for binary operator op_name that each produce an expression instantiated from the expr_template expression template. One overload is defined for each of the qualifiers
&&. For the lvalue reference overloads,
*this is captured by reference into the resulting expression. For the rvalue reference overload,
*this is moved into the resulting expression.
Note that this does not work for yap::expr_kinds assign, subscript, or call. Use BOOST_YAP_USER_ASSIGN_OPERATOR, BOOST_YAP_USER_SUBSCRIPT_OPERATOR, or BOOST_YAP_USER_CALL_OPERATOR for those, respectively.
