BOOST_PROTO_AUTO — For defining a local variable that stores a Proto expression template, deep-copying the expression so there are no dangling references.
// In header: <boost/proto/proto_typeof.hpp>
BOOST_PROTO_AUTO(Var, Expr)
To define a local variable ex that stores the expression
proto::lit(1) + 2,
do the following:
BOOST_PROTO_AUTO( ex, proto::lit(1) + 2 );
. The above is equivalent to the following:
BOOST_AUTO( ex, proto::deep_copy( proto::lit(1) + 2 ) );
