Hi, I am trying to build a mpl::vector from an expression like (string(),ClassA(),ClassB()) To get a mpl::vector<string,ClassA,ClassB> With string, ClassA and ClassB being not enough under control to protoify them with a proto::extends. I naively tried the following grammar struct BuildFlags : proto::or_< proto::when < proto::terminal<proto::_>, boost::mpl::vector<proto::_child>()
,
proto::when < proto::comma<BuildFlags,BuildFlags >, boost::mpl::push_back< BuildFlags(proto::_left),proto::_right>()
{}; Or some typeof variants of it, with no more success and I start wondering if I got on a rocky way leading me to unavoidable doom. Is there a way to do this or I should give up the idea?
