Description
Due to a bug (or perhaps my misusage), I am unable to compose two argument packs, each formed using positional arguments, using the comma operator.
news://news.gmane.org:119/grtmb9$tpq$1@ger.gmane.org Compiler : i686-apple-darwin9-gcc-4.0.1
BOOST_PARAMETER_KEYWORD(tag, x) BOOST_PARAMETER_KEYWORD(tag, y) template<class ArgumentPack> void f(ArgumentPack const & args){
double x_val = args[x]; double y_val = args[y];
}
typedef boost::parameter::parameters<
parameter::required<tag::x>
par_x_t;
typedef boost::parameter::parameters<
parameter::required<tag::y>
par_y_t;
double x_val = 9.0; double y_val = 0.1; spec_x_t spec_x; spec_y_t spec_y; f(
( spec_x(x_val),spec_y(y_val))
); no match operator[<unnamed>::x]
